I had a wierd issue today. I made two hill repeat workouts that I hoped would be fairly similar. One outside, one on the treadmill. Each effort was at similar pace and grade for similar time (about a minute). The issue here is, the efforts outside produced almost 100W more despite the inside effort being a fair bit more difficult. The treadmill effort was much harder on the heart than the legs, and vice versa for outside. Temperatures may have played a role, but I don't feel it'd be that significant. Outside was 30F and dry, inside was 70F with moderate humidity. I had two fans on me during the treadmill run. Same shoes.
I should add my goal here was a power workout. 325W is around my threshold pace outside, but was a VO2max effort here with the incline.
Why would the treadmill be the more difficult effort despite 25% reduced power? I have included the data for discussion. I'd like to hear your opinions on this.
