Our sub 3 hour marathon program is backwards-engineered around beating the three hour mark.
This goal isn’t for the faint of heart…be prepared to train 6 days a week, including several strength training sessions and speedwork sessions.
Who Is It For?:
Experienced runners – good if you’ve already run a sub 4 hour marathon and have the time and motivation to really push your limits!
How Long?:
Five months // 20 weeks.
