I had one track interval session earlier this week: 3min 105% CP * 5 times. During this session my interval power was 261-265w, my pace was 4:08-4:04 min/km. The form power ratio was generally 0.23. Wind power 2-5%.
About 5 weeks ago, I had a fairly flat 5k road race. I ran 3:59 min/km with average power of 258w. The form power ratio was 0.24. Wind power 1-3%.
I am surprised to see that my recent interval session had higher power but at lower pace than my 5k race. The only difference I can think of is the shoes. For the interval training, I had rebel v2 on while for the 5k race I had vaporfly.
Anything else that could contribute to the difference?
