If you love the science behind running, this is the episode for you!
I’ve brought Jordan Santos-Concejero on the podcast today to discuss a little bit of his research on the physiology and the biomechanics behind the art of running.
Dr. Santos started out as a professional runner, but trying to keep up with competitive running and work on his PhD at the same time became a bit much.
Besides, he was much more interested in the research behind what makes a good runner truly great. He’s spent a majority of his research career studying Kenyan runners and their successes.
He breaks down genetics and human evolution and then combines them with modern training in order to uncover what makes professional runners so successful.
If you’ve ever had any questions about your stride, your strike, or even your genetic disposition for physical fitness, tune in now!
Here are some of the topics we’ll discuss today:
- Finding the balance between diet, rest, and training hard
- Why strength training is so important for runners
- Dr. Santos’ research on ground contact time, cadence, and striking
- All of the different factors that influence running economy
- The touchy subject of genetic doping
Questions Jordan is asked:

32:11 What is your research on running cadence and stride?
35:40 Did you find any differences in running cadence with different types of runners?
36:50 Should we just stick with the stride that is comfortable for us?
37:53 What is your research on striking?

40:40 The pros and cons of barefoot running
42:30 How does it feel to be a researcher?
43:50 Where do you see your research going in the future?
47:12 The Final Kick Round!
Quotes by Jordan:
“Training hard is important, but actually it’s more important to get enough rest.”
“I can’t run for fun, I can only run for performance.”
“Strength training is a key training to improve your performance…and reduce risk of injury.”
“Short ground contact time will improve running performance. You can improve your ground contact time by improving your stiffness with strength training.”
“If you don’t do physical activity when you are a kid, some of the physical adaption that [Kenyans] have, you will never get.”
“If you try to change your running cadence consciously, your running economy will be worse.”
“The most economical runners strike on their forefoot.”
