400 Mile Club is devoted to those summer miles. The ones where if you're not up before the sun, you'll seriously consider opting for the treadie. The runs where sweat continues to pour an hour after you've showered. The long runs where losing 8 lbs of water-weight is the norm.
They don't have to be fast, but consistent summer training sets the foundation for autumn success. Need to grow the hay before you can put it in the barn - catch my drift?
You've got 3 months - June, July, August - to log 400 miles.
