s5e25 Gummy Bears, Hobbiton, and Doing "Just Enough": A Real Runner Chat with Dr. Marie Whitt | The Running Explained Podcast

Updated: 2 days ago

In the newest episode of The Running Explained Podcast, Coach Elisabeth is joined by Dr. Marie Witt, a strength coach for runners and doctor of physical therapy, to uncover why so many runners still get hurt during training and what key factors we’ve been missing.

They begin by breaking down a brand-new study from the British Journal of Sports Medicine that reveals single-session spikes in long-run distance, not weekly mileage, are the true culprit behind most injuries, prompting a major reassessment of conventional running wisdom. The conversation then shifts into how strength deficits, underdeveloped single-leg mechanics, and mental resilience play pivotal roles in both injury prevention and recovery.





What They Discuss:

  • Gummy bear fueling and why sour candy hits different

  • What happens when your miles slow way down in the summer heat

  • Shoes, Hobbiton, Regency costumes, and other delightful detours

  • The “minimum effective dose” approach to strength training

  • Why doing less is often the smartest move a runner can make


Sound Bites:

  • “The standout finding (of the study) was that single session spikes in distance carried a much higher injury risk.” 

  • "If you do increase your long run by 30%, but you have been consistently strength training, I wonder if that could help decrease that dramatic potential increase in running injury."

  • "As runners, when we were talking about our injury risk, we don't really appreciate the fact that there are probably going to be in almost all of us, parts of our very important muscles, tendons, ligaments, tissues involved in running somewhere in that chain is going to be a weak link, and it's the weak link that fails first."

  • "Run the race, have fun, do your thing. But we need to have a backup plan."

  • "The number one question I get from every single person I work with is, do you think I would be able to XYZ reach my goal, right...And it doesn't really matter what I think. And even if I thought that it was possible, you won't know until you try."

  • "I think for a lot of us, as long as we are able to get into the consistent rhythm of doing enough, enough probably isn't as much as you think it is."
