We look at the emerging research linking ultramarathoning to a possible increased risk of colorectal cancer, particularly in individuals with inflammatory bowel disease (IBD). The discussion highlights the importance of hydration, nutrition, and recovery strategies for endurance athletes. Vitamin D and gut health also play an important role in decreasing risks. 

Takeaways-
- Some research suggests that Ultramarathoning may increase the risk of colorectal cancer.
- Hydration and nutrition are critical for endurance athletes.
- Vitamin D levels should be regularly assessed, especially in athletes.
- The gut microbiome can change with extreme endurance activities.
- Recovery is essential for preventing long-term damage in athletes.
- Training the gut to tolerate nutrition is important for performance.
- Repeated extreme endurance events can lead to gut ischemia (lack of blood flow).
- Nutrient deficiencies can exacerbate health risks in athletes with IBD.
- A tailored approach to nutrition is necessary for athletes with IBD.
- Understanding the mechanisms behind gut health can inform better training practices.

We love helping provide quality content on IBD nutrition and making it more accessible to all through our podcast, instagram and youtube channel. Creating the resources we provide comes at a significant cost to us. We dream of a day where we can provide even more free education, guidance and support to those with IBD like us.

We need your support to do this. You can help us by liking episodes, sharing them on your social media, subscribing to you tube and telling others about us (your doctors, friends, family, forums/reddit etc). Can you do this for us? In return, I promise to continually level up what we do here.
