30/30, seuil : quelles séances te rendent vraiment plus rapide ?

30/30 intervals, 400 meters, 1000 meters, threshold training, fartlek... When it comes to speed, runners often search for THE miracle workout. The one that will make them progress faster than all the others. But what if the real question lies elsewhere? In this second episode dedicated to VMA (Maximum Aerobic Speed) and speed, we'll see why the best coaches no longer think in terms of the "best workout," but in terms of physiological adaptations. Why do some workouts develop VO2 max, others threshold, and still others running economy? Does the 30/30 interval really deserve its reputation as the king of workouts in French running? And why do top athletes today spend so much time working on their ability to change pace rather than always running at the same speed? Enjoy!
