I’ve found posts here that already kinda explain things, but I’m not sure they are specific to my question.
Rode tonight outside 50 miles in 2:45. Pushed pretty hard a good bit of the ride because the weather’s awesome and I was feeling great. But I don’t know that I was pushing 0.95 IF for 3 hours.
From what I’ve found, IF = NP / FTP
But how does duration play into that? I guess I’m confused on the use of FTP directly on a calculation for a 3 hour ride.
