Parisi Podcast 027-What Endurance Athletes Can Learn from Speed Training

In this solo episode, Coach Casey recaps his training for two ultramarathons completed just weeks apart—a 12-hour 50K in Vermont and the BPN “Survive the Night” 50-miler in Texas. Instead of focusing on the races themselves, he breaks down the three Parisi Speed School principles that shaped his entire prep: keeping weekly speed work to sharpen neurological output, maintaining total-body strength with a focus on relative body strength, and following a general-to-specific progression to match course demands. Whether you're an endurance athlete curious about sprint work, a coach working with runners, or someone interested in how performance principles transfer across sports, this episode gives a clear, practical look at how speed training and strength training can elevate long-distance performance.
