All these mountain bike races are self-supported, so they're actually very similar in the amount of gear carrying by someone doing a thru-hike with UL equipment, as you're carrying everything you'll need from start to finish, including your sleep system. Much of the course for say - the Colorado Trail is difficult enough you're not riding the bike: you're pushing it. This sort of thing [0] I've actually considered trying to hike the Colorado Trail unsupported - carrying everything I'll need from the start (except water) with NO resupplies until the end. My target time would be around 9 days. If you're trying to gauge how strenuous the types of effort I put forth when I go and do the things I do. Anyways, 8 hours seems like an easy day on the trail for sure. 8 hours hike + 8 hours sleep leaves you 8 hours for $Other_Things. Might as well hike some more!
