In this episode we talk with ultrarunner Alyssa Amos Clark about:

• 10 years in the sport
• How she's managed nutrition and hydration
• Caffeine ... when she skips and when she takes it

Originally from Vermont, and now living in San Diego, CA, Alyssa Clark thrives on competing in the gnarliest and toughest running races she can find. But her greatest passion is mountain running, and she’s working on becoming the best 100+ mile runner she can be, both for racing and for long distance trail adventures.

Alyssa has won the 2023 Canyons 100 UTMB Major and placed 11th at UTMB 2024. She not only won the HURT 100 twice, but in 2025 also became the first woman to break 24 hours and set the new course record. In 2022, she won the Moab 240, placing third overall, and has also won the Puerto Vallarta 100 miler, San Diego 100, and the Ouray 100. In 2022, she ran 95 Marathons in 95 Days, setting a Women’s Guinness World Record for consecutive days running a marathon. She was also the first woman to set a Supported FKT on the 350-mile Pinhoti trail, and set an FKT on the Lone Pine to Mount Whitney Summit via the Mountaineer’s Route. She has run and competed all over the world and seeks to take on the most challenging ultras across the globe, and consistently places in the top 5 overall. She’s also been coaching athletes for the last five years, including a stint instructing at the Naval Fitness Facilities in Naples, Italy. Now a coach for Uphill Athlete, she’s also the company's podcast producer and host, and director of training plans. 

She is also committed to empowering women to get out into uncomfortable spaces and seeks to provide a community and support with coaching and mentoring.
