Yesterday, Molly Huddle broke the American 5k record for 17 year olds, breaking her old mark of 17.04, running a blazing 16.23 on a certified out and back road course. Opening with a 5.01 mile, Molly won the race overall, beating the first place male by at leat 20 seconds.
I think this was off of just base training, no speed work.
Now she's on her way to Notre Dame for preseason XC training. Hopefully we'll continue to see new records set by this emerging phenom.
