I don't know if I consider myself a "climber", although I do a lot of climbing and enjoy it. I'm almost 6'3" and 165 lbs, I consider that fairly light for my height, but would consider under 140 lbs light for an elite climber.
Climbs I've conquered:
All 6 in the Everest Challenge Stage Race (Eastern Sierras)
Mosquito Flats- 22 mile climb up to 10,250', avg grade 5%
South Lake- 20.5 mile climb up to 9,850', avg grade 6%
Ancient Bristlecone Forest- 21 mile climb up to 10,100', avg grade 6% (last 3 miles avg 10% )
3 other climbs around 8 miles each

Mt Baldy via GMR and GRR- ~27 miles
Mt Baldy via Mt Baldy Rd- 13.5 miles @ 8%
Palomar Mt via South Grade
Onyx Summit- ~20 miles up to 8,700'
Oak Glen- 5 miles at 6.7%
Just about any steep hill over 1 mile in Orange County

Plus a bunch of climbs under 5 miles and all the ones that escape me at the moment
