I really don't know b/c I don't do the whole GPS or Cyclocomputer geek crap...but my friend mapped out this climb that I do on my singlespeed...it came out to about 1500 vertical feet in 45-50minutes or so. 2:1 was perfect for it...just the right amt. of pain
It's like 250 feet of vert...then we turn around and go straight back down and do it again...6 times in a row.
Anyhoo...is this average for you XC geeks? Less? More? Weak sauce?
