Speed Work

Speed work, was 200M on - 200M off for 5K, interesting workout, but I had never done anything like it before, so I started off too fast, and ended up having to walk during many of my 'off' phases instead of just lightly jogging. AHR for the workout was 171, with a max of 181 on the final repeat, and hitting 180 a few of the other repeats. 'On' repeats of 45s, 49s, 49s, 49s, 52s, 53s, 52s, 49s, 50s, 53s, 52s, 52s and 54s. My 'off' repeats ranged from 1:06 to 1:36 as I had to walk during all but the first few. Temp was around 78F with a dewpoint of 61F, so very comfortable. I'll probably try to do this sort of workout again some time, as it was interesting.
