6 x 2 minute fartleks

Well it's the day before the Patriotman 1/2 ironman in Freetown MA. Jill, myself, Courtney, and Sara are sharing a romm at a place near the start. While they drove the bike and run course I did a few mile run with 6 x 2 minute fartleks thrown in for good measure. Man was it hot! Not sure on the distance.

Average HR 171 for 46 min.
