#13 What happens at Mile 20? Something about hitting a wall? With Star Blackford
Training Talk Video #13 is LIVE and this week our very own Star Blackford joins us to share what happens at Mile 20 (hint: you may have felt it before!).
If you’ve started your long runs in training, or have run marathons before, you know the ominous feeling of “Hitting the Wall”—the sudden fatigue, heavy legs, and “I can’t take another step without collapsing into a pile of mush” feeling.
“Hitting the Wall” is your body’s way of converting fat into glycogen— which is the sugar that comes from carb-loading. However, the fat-to-glycogen conversion takes about 10-15 minutes. This is why the extreme fatigue and heavy legs feeling lasts around 15 minutes before a “closer-to-normal” energy level - or second wind - kicks in! You’ll still have the fatigue of the miles with you, but hopefully, it won’t seem as overwhelming.
What are some of your tips to make it through “Hitting the Wall”? Let us know in the comments!
Thanks for watching and stay tuned for next week’s video!
