Highly individual, but out of super early or super late, I would go for super early. By the time a long day is behind me, my motivation to rip my legs off late at night diminishes quickly. With early morning, I have my workout done before most people wake up and I’m pumped for the day.
I’d be looking to cut down my pre-bike time though. I’d be getting all my bike and kit ready the night before, alarm goes off and I’m on the bike 5 mins later. Most rides are 60-90 mins long mid-week, which I find very doable without any nutrition prior.
There’s a pretty deep thread here that’s worth checking out too:
