Yesterday was one of the harder rides I've done. I sought out some climbing and did two laps of
this route. 4:00, and the first lap was considerably faster than the second. IF for the first hour was .94, for the first two hours was .91, and for the entire ride was .83...slowed down towards the end. TSS was 276, 2455 kj. Part of what tired me out was a decision to climb in the 50-60 rpm range to add resistance. Just over 3000 feet of climbing - not much for those who live in hilly country, but it was the best I could find.
