Running with Dr Will

Sports scientists have consistently shown that the mean upper limit of exogenous (supplemented) carbohydrate oxidation rates is 1.5 g/min or 90 g/hr. Yet, we're hearing reports of endurance athletes taking on well above 100 g/hr. Why? Is anyone basing their carbohydrate intake on personalised testing or a simple "more is better" approach?

A few weeks back, I wrote about how I’m giving up on ultrarunning to pursue a new challenge - running fast. What do I mean by “running fast”? My ultimate dream goal is to run under 15min for 5km. I ran 8:54 for 3km a couple of years ago, so I think (hope) I have the potential for a sub15 performance. I just need to hold the same pace for an extra 6min….As I transition away from being an ultra-marathon runner to a track athlete, I find myself delving into the realm of anaerobic work capacity, critical power, and the power duration curve. Anaerobic work capacity refers to the physiological ability to perform high-intensity activities that heavily rely on anaerobic energy systems, specifically the phosphocreatine and glycolytic pathways, which generate energy without the need for oxygen. It plays a crucial role in shorter-duration races, such as track events, where explosive bursts of power and speed are paramount.Read the full blog - https://www.drwilloconnor.com/blogUse my training zones calculator https://link.drwillo.com/calculatorsFollow me on Instagram (DMs welcome) - https://www.instagram.com/drwilloconnorStalk my training on Strava - https://link.drwillo.com/strava-profileLinks and resources to help your running.1.

I got a message on Instagram from a guy with a goal of running under 1:50 for the half. He asked if he should adjust his 1:45hr half marathon training plan or leave it the same.I immediately got annoyed at these silly finish-time training plans because they do more harm than good. There’s often no ability to personalise the plan to your thresholds and intensity zones.I believe your physiology should predict your finish time rather than letting a finish time dictate your physiology.Read the full blog - https://www.drwilloconnor.com/blogUse my training zones calculator https://link.drwillo.com/calculatorsFollow me on Instagram (DMs welcome) - https://www.instagram.com/drwilloconnorStalk my training on Strava - https://link.drwillo.com/strava-profileLinks and resources to help your running.1.

I did it! I used the run-walk method to run my fastest marathon - 2:37:49. I'm seriously struggling to wrap my head around how I walked for 6 minutes and still got a PB. How Much Faster Without Walking?After the race, the most common question/comment was, “Imagine how fast you would’ve run if you didn’t walk!”. I've put a lot of thought into how much faster I could have run in this alternative universe where I didn't walk. Unfortunately, the answer is more complex than 3:52 min. Which is the amount of time I "lost" to running. The thing is, I’m not losing time by walking. I’m conserving energy. Time is constant. You can’t save time or lose time. Time is never in your control. However, energy is controllable. You can store it, spend it, or transfer it. When running a marathon, the critical variable you have to control is your energy output.Suppose energy output rather than time (or pace) is the critical variable in marathon performance. In that case, we should look at the maximal potential energy output across the 42.2 km rather than the maximal sustainable pace, which is a product of your energy usage.Run-walk Training Bundle.

Trying not to walk in a marathon isn't noble. It's potentially detrimental! I've run-walked a 2:45 marathon, and I'm planning to run-walk a lot faster in my next marathon (April 16th, 2023).My run-walk method is the next iteration of Geoff Galloway's run-walk-run method. Using my background in sports science and practical experience as a long-term runner, I've developed a run-walk marathon method that will work for fast and slow runners.Learn more and try my run-walk method for yourself with my Run-Walk Training Bundle (only $49nzd) - https://link.drwillo.com/run-walk-bundleRead the full blog - https://www.drwilloconnor.com/blogFollow me on Instagram (DMs welcome) - https://www.instagram.com/drwilloconnorStalk my training on Strava - https://link.drwillo.com/strava-profileLinks and resources to help your running.1.

Head to https://link.drwillo.com/runfasterwithdata to get a scientifically backed system for taking runners training from an unstructured mess to a result-driven system that provides accountability, confidence, and fitness.While I'm a competitive runner now, I was once a complete newbie who thought harder, faster, and further was the only way to train. Over the last decade, I've achieved a PhD in Sport & Exercise Science, run countless races, and coached hundreds of runners. Over that time, I developed my ABCs of building fitness, the backbone of the #fasterwithdata system.

I’ve been getting coached by an AI via the Athletica platform, and as much as it pains me to admit it, my AI coach is really good. TL:DR. If you’re a keen data geek interested in training and tech, try AI coaching for your next race. At $99 for six months, what have you got to lose? If you’re more of the “I’ve got no idea what I’m doing, I just need someone to tell me what to do” type, then I’d say buy an off-the-shelf plan or get 1:1 coaching if you can afford it. Regarding Athletica specifically, the lack of an app, running power, and some integration features leaves the user with much to do compared to the likes of TrainingPeaks or even the old-school ‘print off your plan’, but being able to mentally offload the stress of thinking about what training you need to do is massively uplifting. (Short-term opportunity, AI & Dr Will Collab for $199/month - email me)Read the full blog - https://www.drwilloconnor.com/blogFollow me on Instagram (DMs welcome) - https://www.instagram.com/drwilloconnorStalk my training on Strava - https://link.drwillo.com/strava-profileLinks and resources to help your running.1.

🛑 Stop ignoring your data ⌚, and start using that expensive wrist computer to optimise your running.🏃Heart Rate ❤️‍ running is the easiest way to build your base fitness. Are you using your heart rate monitor to its full potential?🙄Here’s a simple, four-step strategy for strategically using a heart rate monitor for your running.🏃🏃🏃🏃🏃🏃🏃1. Find your lactate threshold & set your training zones.You’re likely using the default zones your watch gave you….. And they’re likely WRONG 🤦.👉 Go run 30min hard, and take a lap at 10min, and the end. The average of the last 20min will be your threshold HR (and pace & power). (My zones calculator https://link.drwillo.com/calculators)👉 To hard basket? Use a REAL max HR from the last 6 months.2. Create a HR controlled training plan using training zonesOnce you’ve set your threshold and zones, you can create an 80/20 training plan to build your aerobic base!👉 Example: 80% of your running should be done in HR Zone 1 & 2. 20% can be hard Zone 4+.90/10 is better for base building, but 80/20 ensures you don’t get bored while maximising your RECOVERY! (I covered 80/20 running on last week's podcast)3. Add specificity with pace and powerUse the 20% hard running to maximise your training time and eliminate your weaknesses! HR gets a bit messy above threshold, so use pace or power for your “fast” intervals.👉 Want to run a fast 5km? Target Zone 5+ workouts with plenty of SPEED👉 Need to improve strength? Smash out some hill reps👉 For example, I need to improve my threshold for an upcoming 10km, so I’ll target long (~1-3km) Zone 5 intervals and short (<2min) Zone 6 speed workouts.4. Hold yourself accountableThat fancy watch on your wrist does more than upload to Strava 😲. 👉 Check your data after each run. Your easy aerobic runs should be 100% ZONE 1 - 2. 👉 DON’T use average heart rate. Just because your average heart rate was in zone 2 doesn’t mean you spent the whole run in zone 2.👉 For example, you may have an average heart rate within zone 2, but you ran with a zone 3 heart rate on the uphills and a zone 1 heart rate on the downhills. THIS IS NOT maximising aerobic fitness. It’s nonspecific grey zone ❌.Read the full blog - https://www.drwilloconnor.com/blogFollow me on Instagram (DMs welcome) - https://www.instagram.com/drwilloconnorStalk my training on Strava - https://link.drwillo.com/strava-profileLinks and resources to help your running.1.

If you think running more is your answer to your next PB, you are most likely wrong.79% of runners end up injured AND running more than 65 km (40 miles) per week is associated with higher injury rates (Van Middelkoop, et al 2008).Adding some extra mileage to your weekly schedule is easy. Running a targeted race-specific workout that builds fitness and speed is complicated.Most of the time, runners know what training they need to be doing, but they lack the structure.Find out more about coros https://link.drwillo.com/corosOptimise your running and SMASH your next event with my ABCS to Running PBs formula https://link.drwillo.com/reigniteyourrunningFollow me on Instagram (DMs welcome) - https://www.instagram.com/drwilloconnorStalk my training on Strava - https://link.drwillo.com/strava-profileLinks and resources to help your running.Steal my formula for smashing mind-blowing running PBs FOR FREE! https://link.drwillo.com/stealmyformulaBuy one of my $59 DONE-FOR-YOU Training Plans. https://link.drwillo.com/leadtrainingplans

Here’s what your running probably looks like;You mentally sign up for an event but don’t actually sign up because that’s a bit too much commitment upfront.Start training… without a plan. Or try some free generic plan from Garmin or whoever.Pretty much ignore the plan and run everything steady because easy running feels like a waste of time and looks lame on Strava.If you do decide to do some intervals, you smash the first few and then struggle through the last couple or just give up.You miss a few days of training because you haven’t committed to a training plan to help you plan ahead, so family, work, travel and life fill the spare time you hoped you’d have for running.All of your training and race paces from 10km - marathon begin to merge into this small bandwidth because you haven’t been training for fitness or speed. You’ve just been sending it when you had the chance.Race day finally arrives, and you’re totally unsure if you can achieve the arbitrary finish time you’ve chosen for yourself.After the race, you know you could have run faster, but you’re not really sure how.Can you relate?

If not, you could be doing more harm than good to your training and performance!💪 Grey zone training is pushing too hard without the right intensity and can lead to fatigue, injury, and plateau. On the other hand, Zone 3 is the ideal low-dose strength and stamina-building zone.😲 But beware, zone 3 can quickly turn into grey zone if you push the pace too hard. That's why it's important to find your thresholds (pace, power, heart rate) and set your training zones.💻 My simple three-step process for setting your running thresholds:1️⃣ Get a baseline measurement of your running performance with a 30min TT.2️⃣ Determine your threshold levels based on your average pace/power/HR of the last 20min of your 30min baseline measurement.3️⃣ Create training zones based on your thresholds. https://link.drwillo.com/calculators📝 Don't let grey zone training ruin your running journey.

Join me at my LIVE Masterclass - March 13th https://link.drwillo.com/reigniteyourrunningAnother running event, another heat stroke 💔 As a runner, we all know the feeling of pushing ourselves to our limits, but what happens when our body can't keep up? It's time to talk about the real consequences of overheating and why it's crucial to listen to our bodies.Have you ever noticed that no matter how hard you try, the same thing keeps happening during races? Your body temperature rises, you feel dizzy and disoriented, and you can't seem to shake it off. That's because repeated overheating can have a lasting impact on your body, specifically on the hypothalamus.The hypothalamus plays a critical role in regulating our body temperature, but overheating can cause inflammation and damage, leading to a decreased ability to regulate temperature effectively. This makes us more vulnerable to heat stroke, even in low ambient temperatures during a race.Read the full blog - https://www.drwilloconnor.com/blogFollow me on Instagram (DMs welcome) - https://www.instagram.com/drwilloconnorStalk my training on Strava - https://link.drwillo.com/strava-profileLinks and resources to help your running.1.

Last year, Tarawera was cancelled due to covid, which was lucky for me because I trained so hard that I got a sacral stress fracture a couple of weeks before the scheduled race date 😥. In 2021, I raced totally underprepared and pushed myself so far beyond my physical capabilities that I collapsed at 95km (yes, 95!). I was carried out of the forest on a stretcher.

I doubt it.I can almost guarantee you are running too fast rather than too slow.Everyone thinks that performance comes from hard workouts.In reality, your best performances are predominantly dictated by your aerobic base. Not your ability to run 10x 1min fast.Running longer than 60min requires the ability to utilise fats maximally, spare carbohydrates, and buffer the acidity of lactate production to maintain maximal running economy for the duration of the event. At no point are you required to run ‘fast’. Your aerobic system contributes 98% of the energy required for events lasting 60min or more. Therefore, your most significant potential to get faster lies in building your aerobic base.The biggest mistake I see runners make is thinking they need to run fast to get fast. Read the full blog - https://www.drwilloconnor.com/blogFollow me on Instagram (DMs welcome) - https://www.instagram.com/drwilloconnorStalk my training on Strava - https://link.drwillo.com/strava-profileLinks and resources to help your running.1.

Tapering is always hard. You need to freshen up, but you still have to do some hard workouts so you don't get stale. Otherwise, the race will be too much of a shock to the system. At the same time, you can't thrash yourself, or you'll start the race cooked.Tapering requires you to be super in tune with how you feel daily to avoid overdoing it.At the fundamental level, tapering is a progressive reduction in training load. Runners will reduce their intensity, duration, and sometimes frequency to increase their recovery time, leading into key events.I believe there are four distinct durations for tapering;Ultramarathon (5hrs+) = last big workout, four weeksMarathon (2 - 4hrs) = last big workout, three weeksHalf marathon (1 - 2hrs) = last big workout, two weeks<10km (< 1hr) = last big workout, one weekRead the full blog - https://www.drwilloconnor.com/blogFollow me on Instagram (DMs welcome) - https://www.instagram.com/drwilloconnorStalk my training on Strava - https://link.drwillo.com/strava-profileLinks and resources to help your running.1.

Auckland Marathon 2022 was set to be my best marathon. My training had gone perfectly. Probably my best ten-week block of training EVER. I don’t think I missed a workout, and that wasn’t through being super addicted to training. I loved every run and only began to feel tired in my last ‘training’ week before my taper (3-weeks from the race). I felt like I had a system that was working.What did my training look like?After building back from Covid, I did two major blocks of training. Each block was three weeks, with a one-week recovery in between. Each week was about 650 TSS (training stress), 9hrs, 120km, 1000m elevation. I did a midweek threshold workout and a weekend marathon tempo workout each week. The rest of my runs were easy, mainly off-road and hilly.I specifically made a point to slow my easy runs, which greatly impacted the quality of my workouts and my day-to-day recovery. For reference, most of my easy-aerobic runs were around 4:30-5min/km, 80% LTHR, 80% FTP. Last year, in building up for the Tarawera Ultramarathon, I realised that when my weekly training load is over 100km/wk or 8hrs/wk I can’t run my easy-aerobic runs at the top of my zone 2 (85-88%). Otherwise, I struggle to recover from the big weekend workouts. You can follow me on Strava to track my training.Marathon WorkoutsI did four marathon-specific workouts, the biggest being 30km @ target marathon power three weeks out from the race. I ran the last 10km at the top end of my goal power, averaging 3:35min/km and heart rate staying in zone 4 (sub-threshold). I felt great. It gave me a lot of confidence that I could run in the low 2:30s come race day. Race WeekMy 2-year-old son gets gastro on Tuesday (race is Sunday), and then my wife gets the bug on Thursday. I felt fairly average from Wednesday but never appeared to have contracted the bug. The day before the race, I felt like a truck had hit me. I told Emma how disappointed I was that I wouldn’t be able to race to my potential. However, that afternoon, I felt 100% times better and thought I had finally experienced that taper-week bounce. Race morning, it was pouring with rain, and I mean torrential rain. I couldn’t find my car key, and then I lost my hotel key. Honestly, it felt like the world didn’t want me to do this race.Process GoalsI felt so bad the days leading into the race that I made a point to write out non-outcome goals that would make the race a success. Expressing myself, having fun doing what I love, and being proud of my effort were the key goals I put together. Once I had these goals in place, I felt I lot better about running a race in which I may not be able to perform to my physical potential. The RaceI had my watch on 5km laps with my screen showing lap power, lap pace, real-time HR, and real-time power, which gave me a good average of what I was doing rather than looking too much into each km or mile. I’ll break down my race in each of these 5km segments.Read the full blog - https://www.drwilloconnor.com/blogFollow me on Instagram (DMs welcome) - https://www.instagram.com/drwilloconnorStalk my training on Strava - https://link.drwillo.com/strava-profileLinks and resources to help your running.1.

I hear the 3hr marathon goal thrown around A LOT. A large pool of runners I work with are 35-45 year old working professionals. They come to me and say, “I want to run sub 3hrs. Is that realistic?” They’re often concerned they might have left it too late. Here’s what you need to be able to do for a sub-3hr marathon goal to be realistic.The first number you need to look at is your threshold pace. You want to have a threshold of around 3:50 - 4min/km (6:10 - 6:26min/mi), which is about a 39min 10km or 1:26min half marathon. If you cannot run a sub 40min 10km, you have next to no chance of running sub 3hrs. Your sub-3hr target pace is 4:16min/km (6:52min/mi), which means your 1km/1mi splits will drift between 4:10 - 4:20min/km (6:42 - 6:58min/mi). Unless you’re running on a treadmill, you NEED to be capable of running 4:10min/km (6:42min/mi) without going over your threshold.Suppose your threshold is slower than 4min/km (6:26min/mi). In that case, you will burn too much muscle carbohydrate, accumulate lactate/acidity, and subsequently build fatigue too quickly, which will have you hitting the wall before the race end.There’s more than one threshold…Read the full blog - https://www.drwilloconnor.com/blogFollow me on Instagram (DMs welcome) - https://www.instagram.com/drwilloconnorStalk my training on Strava - https://link.drwillo.com/strava-profileLinks and resources to help your running.1.

Does maximum heart rate influence performance? Short answer, no. Cardiac output matters.Your maximum heart rate has a higher chance of DECREASING as you get fitter. I’ll explain why. The term “heart rate” describes the frequency (in beats per minute, BPM) at which the heart is beating at a given point in time. Combined with the stroke volume (the amount of blood ejected from the heart per beat, SV), we get the total quantity of blood being pumped from the heart to circulate around the body per minute (the cardiac output, CO). Blood carries oxygen and fuel to the muscles and removes carbon dioxide as a waste product. At rest, our need for this process is low, so the heart can beat relatively slowly to fulfill requirements. However, during exercise, the demand for blood increases dramatically, and, as the ability for stroke volume to increase is low, this is primarily met by increasing heart rate, making heart rate a good indicator of how hard the body is working to produce metabolic power. Consequently, heart rate has been used by athletes and coaches for several decades to objectively measure exercise intensity and prescribe training.Through the development of wrist-based HR sensors, many runners have started utilising heart rate in their training, which has led to some dubious ‘experts’ touting bro-science about HR and fitness. Despite heart rates’ advantages over earlier training metrics, such as perceived exertion, heart rate is not a perfect training tool.One number I see thrown around is maximum heart rate (HRmax). The higher your heart rate the better runner you are or the better you are at pushing yourself.
