My day: longest fasting cycle ride (so far!)

[Subtle_badger]

After a late meal last night, I decided I would see if I could do my previous habitual ride of 50-60km without eating today. I haven't done that sort of distance without a meal.

I set off mid afternoon, on a flat loop. Finished the 60.4 km (about 37 miles) just as I hit 21 hours fasted. Felt great on the ride, though a bit hungry a lot of the time - nothing I couldn't resist. A few times I flagged - mostly notably just 6km into the ride when I "realised" that I wasn't going to hit my goal. I powered through that moment and proved myself wrong. Similar flagging was just ignored, and was forgotten moments later.

I did not set any records on the ride, but I felt good enough that I thought I might - I wasn't close. At one point - halfway across Runnymede for you history buffs - I felt a moment of pure joy which has been missing from a lot of my rides recently.

Scoffed a lot of food through my extended 2 hour OMAD window. 1300kcal and 21g of carbs, so happy with that after eating to satiety.

Feeling good now, though wide awake. Might try to repeat the performance tomorrow - with a different route, for variety.

Ugh. I just took my BP. Pressure is fine 116/73, but pulse is still elevated, around 85-90 😔 Hopefully it settles overnight.

Wow! Fantastic performance.

My resting HR stays high for 48hrs after endurance fasted state exercising too. I hope it helps to share similar anecdotes

Thanks. I think you are right. I'm a little disappointed; I wanted to be completely fat adapted so my body did not regard yesterday as stress, but my hr tells the truth.

Or maybe the stress was the ride itself, which was my longest of the year. Still disappointing: I'm either unfit or not fat adapted.

Or both 😔

I assumed it was a by-product of exercise-induced thermogenesis/increased metabolism, and therefore a good thing?

Am I just clutching at straws

Thank you, I like your spirit.

I don't think an elevated resting HR is ever a good thing. It says your body is under stress. I am hoping I can get my RHR back into the low 60s or even 50s, it's currently in the 70s. It was very disturbing to see it in the 90s last night.

Back in the 70s again today, so I haven't made it worse.

Well done, Subtle_badger!
