The J challenge used to be a 70 mile MtB with something crazy like 14,000 vert. Big J did it i think. Freaky. I think 5000 vert is a very respectable workout no matter what your gear is. Skis, Bike, Hike, that's a pretty good up. Greg, you're ready for the Vermont MTB fest.!
You said it. I once did a 65 mile road ride with almost 6k of climbing, and I was pooped.
