Hoooray!!! The track was locked again, so I used the 1/2 mile dirt track, which I actually really like. I did 4 repeats of 1/2 mile, rather than the suggested 5 x 600 meters (ends up being about the same amount of time running my ass off). As I was calculating my goal time for the intervals, I remembered that 1/2 mile VO2 intervals are the famous Yasso 800s!

From what I understand, Bart Yasso suggests doing 800 meter intervals at your goal marathon pace, in minutes. So, for my 3:40:00 goal for the marathon, I would do the intervals in 3:40. He suggests building up to 10 repeats, and I"m only doing 4, but same idea. So 3:40 was my goal, which is a 7:20 pace. This is what I believe to be my VO2 max (not a coincidence, that's the point of Yasso's theory). Anyway, I ran much faster than that!!! :) And it felt GOOD. It was a completely different experience than my first Interval workout a couple weeks ago. I think the fact that it was morning vs. afternoon makes a big difference, I was feeling pretty fresh. Plus the intervals were just a little shorter (.5 mile vs. .75 mile) but I think that made a difference too. I was just feeling really good. :) I know this isn't enough reasoning to change my marathon goal, but I'm feeling really confident that I can run 3:40 in Sacramento. :) YAY!!!
