PM: Crossfit Endurance 40:20 x 5

40 seconds on: 20 seconds off. 5 rounds, all out sprints.

Did this on the path behind our house with Nick calling "start" and "stop" to me. I have no idea how much distance I covered. On the first round I ran clear off the path and got most of the way up the hill of our street before I got to rest. Then I had to come down the hill, which was very fast. For rounds 3-5 I just ran back and forth over the flat part of the path and the road, which I think was a better way to go. Sticking to the path allowed my to try and beat the number of out and backs I did, too. I was averaging 4 out and backs, but got almost 5 on the last round! (No idea of actual distance, though!).
