I did a 20 (.5) miler this past weekend. Once you get into these big numbers those halves dont really count for much.
What I learned:
Clifgels are the best
I am (maybe) not totally screwed for this marathon
And then of course a post-run smoothie of banana, peanut butter, almond milk and cocoa powder is the greatest.
Then I RICED my lower body at work. Compression socks + ice + foam rolling =quick recovery.
