I have a good way to establish a frame of reference here.
The hiking version of the Colorado Trail is 485 miles and about 75,000 (actually don’t see the elevation profile for the hiking route but that this the elevation gain of the Bike version) feet of elevation gain at an average elevation of 10,347 feet. The average hiking speed is 5 weeks, so the average Thru hiker is averaging 16 miles and 2,500 feet of elevation gain a day. Since the trail covers 5 mountain ranges from Denver to the SW, that should give you a good idea of what a person can expect to cover on a sustained day to day basis. I would guess that for hunters, it would be more like 8 miles and *as much as* 2,500 feet a day since they are generally moving slower and often off trail, though are deliberately going to high points instead of around them, but if you’re outpacing a Thruhiker, you probably aren’t hunting effectively.
