Re-run of the Arboretum event from June. I wanted to be clean today, and keep moving. I did well at moving. One small bobble on 10. Then, as I was approaching 15, I saw that I could possibly break 39 minutes (for 10 min/k). So I pushed really hard.
Mike and I both knocked off work a bit early today, so we went for a nice bike ride together. I felt I was pushing harder than last time, Mike felt it was easier. Was he right because his HR was lower? Or was it cooler, so his HR was not a good guide? Was I right, that the perceived effort was harder, but I was tired and an easy effort felt hard?
