The Gran Fondo will be shorter overall with *WAY* less climbing than the Cabot Trail I did in 2019. On the Cabot Trail ride none of the days were more than 100km but there was ~4100 meters of climbing, 1950 meters on day 2. The Fondo should be "easy" compared to that ride and I ate nothing before supper then, too.
I have no way of measuring power at this time so I have no idea what I output. If I could afford that kind of accessory I might get a faster bike first. lol
Not sure that is something to be proud of.
In his podcast, I believe even in the episode with Inigo san Milan, Peter Attia talks about his attempt at achieving a ketogenic state, and even then he mentions that he could eat a ton of carbs and stay ketogenic because they would just get used up as fuel during exercise.
Anyway, fat is slow burning, you can train yourself to use it as a fuel source exclusively, but there will be a limit to your power output. At some point where you are outputting too much, fat won't do it anymore.
