Last night’s track workout was 12x400. Based on the Hansons Marathon Method, for my goal pace of 23 minutes for a 5K, I should have been running 1:58/400. As it turned out I was able to hold between 1:44 and 1:48 for all 12. I was pretty pleased with myself. I also captured my heart rate during the workout. It is kind of cool to see every fast 400 followed by 400 recovery and then regrouping. Besides the first one when my heart rate spiked into the 190’s, my heart rate was in a reasonable zone between the 160’s and 180’s.
