Bandeira is my longest. So that’s 6 hours. Uuummmm…lessee…I also did Excelsior, which is 4:15. I’ve done Highland…that’s 5 hours.
Long, but not extreme. I bet there are several on this forum that have done 10+ hours.

4.5hrs has been my max length one, did it this past winter (Hoffman) I also did a 4hr session this winter as well (I was kind of blending it with SSB at the time to build). At the time I was hoping to build a massive base, and of course soon after I did that I went on vacation in Feb and it kind of set me back lol I would love to get to some 5-6hr sessions sometime. One of the big “last frontiers” of endurance I’d like to conquer is to ride back to back centuries on a weekend

back in March I vEverested Alp du Zwift. 15 hours. And yes, it was horrible

I’ve done a several 3 hour Zwift group rides which weren’t bad (except for the one with the unexpected 45 minute climb at the end. Always take a peak at the route profile before you start . . . ). Music plus the carrot of sticking with a group makes the time pass similar to an outdoor group ride. The longest pure indoor workouts I’ll do top out at 2 hours.

Longest has been 4 hours. Back to back 3 hours on weekends during the winter is normal. Weekday rides during the school year (teacher) tend to be 90-120 min.

Curious as to how long your ascents were, on average…and what kind of wattage you were doing.
My longest has been 15hrs. Average is probably 1.5-2hrs.

This was easy:
A little century warmup a week before the double. Plotting my return (2021 or 2022) to the double century scene and snagging a California Triple Crown jersey (3 doubles in a calendar year).
On the other hand was only able to snag a ‘triple crown’ from week 3 of Traditional Base High Volume I
had to tap out of the Sunday ride. Never going back to that >2.5 hour trainer dark place. never. ever. again. 
y’all doing >3 hours on the trainer are seriously hardcore.

I averaged 150 watts every climb, 1.5 hour ascents. Was really consistent in that regard. If I remember right I was around 64 kg’s at the time if that helps
Thanks…when I was mapping it out, I was using ~1.5 hours / ascent…was planning on slightly higher wattage, but I also have a few kilos on you, so sounds pretty similar.
Nice job!!
I was going to say that Disaster Day in 2018 was my hardest/longest indoor trainer ride.
Avg session between 70 and 90 minutes.

Respect for making it 4+ hours on Disaster Day.

10 and a half hours for an Everest! Though “only” about 9 hours of actually riding I guess, as there was about 90 minutes of descending which I used to hop off the bike to stretch, eat, change, pee, etc.
Very much a one off. Average trainer session is about 90 minutes. I do 2 hours quite often but very rarely more than that. Partly because you simply don’t need to train more than 2 hours indoors. Partly because it’s boring - 2 hours is great for watching a movie, but I don’t want to watch back to back movies and after more than a couple of episodes of even the best TV show or podcast I’ve had enough. Partly because for some reason my family find it almost impossible to understand me sitting on the trainer for >2 hours, even though they have no problem with me disappearing completely for much longer than that on an outdoor ride! I think it’s being able to hear me in there and the fact that they know I’m watching TV, longer rides tend to get increasingly beset by interruptions of “are you done yet?”.
At the beginning of lockdown we weren’t allowed to train outside at all for a few months and I did do some longer rides then, trying to replicate my usual training which nearly always includes a 3.5-5 hour weekend ride. It was just counterproductive for me though, as spending that long on the trainer in one go sapped my motivation (and depleted my stock of things I really wanted to watch…) and I’d end up having days off. 10 hours/week of riding 1-2 quality hours every day is much more effective for me than 10 hours/week with 1 really long ride and 2-3 days off the bike or riding with low motivation.

wow. 
Never say never. Turned on the Giro, lined up my food/hydration, and didn’t sweat the details.
3:15:31 elapsed
3:00:37 moving
Air outside was smoky and crappy air quality (AQI 158). Desperate times call for desperate measures. My Strava feed is full of crazies riding outside.

Same as a couple other guys, 14 hrs total time everesting, about 12:30 moving time, and in no rush to ever do it again

Just curious about opinions on taking a break during these looooooooong indoor endurance rides.
I’m probably going to be attempting 3hrs+ indoors for the first time this winter, and I’m fully expecting to need a 5 minute break at some point just to aleviate saddle discomfort! Will this detract much (if at all) from the goals of the workout?
