I wish I was the one creating the heat, but the sun beat me down. I went out to do some more 90 second interval, this time seven up them up a steep climb. This is my third consecutive week of these intervals. My legs felt good, but I was severely limited by the heat. I drank four water bottles in less than 2 hours, and I don’t think that was enough. Below is the temperature graph:

To remind you, two weeks ago I did 6 intervals up hill, then last week I did 6 intervals on level ground. Below is a comparison of the three sets:

Analysis? Overall I’m pleased with the workout. I wasn’t sure I could finish it, and didn’t think it was ‘blog worthy’. It shows the effects of heat though. The workout didn’t provide the strength training I was hoping to get, but it provided high exertion with reduced blood flow to the muscles because of more blood flow to the skin for cooling. Also, it will provide heat acclimatization training which should pay off if I end up riding or racing when it is hot.
