Discounting the potential for extreme heat in the GC, I'd say Whitney's tougher than R2R. Same elevation gain, but you're 6000' higher and the trail is significantly rougher. Now if you make it R2R2R in a day, that's definitely harder!
We did R2R2R in a day. Still think Whitney is harder...............................................DUG
I haven’t done R2R, let alone R2R2R, but I’m pretty sure R2R2R is harder than Whitney. I HAVE done a Whitney double. THAT might be harder than R2R2R. Or maybe not. It depends on whether you like hot weather better than thin air.
It wasn't hot when I did R2R2R. Either time. R2R2R is a lot easier to run, with better trail than Whitney. Less need to carry much water, allowing for even lighter loads. I've actually done both and feel that Whitney is more difficult. When you try R2R2R, don't go when it's hot. Simple......................................DUG
