I've done sea level to 200om in Spain, on road but with panniers. Only realised after the holiday quite how much up we'd done. We are all stuffed that evening
5300m in Bolivia, down Chacaltaya, where the world's highest ski resort is. The ride starts with mega rocks and scree, high altiplano scenery, and ends with semi tropical rainforest and dusty corners on lush doubletrack. Amazing…
@MH, I didn't do the 403 which was a shame – Strand Hill and Farris Creek were superb (in different ways – seeing bear claw marks on the aspens made me get a shift on…), as was Upper (and Upper Upper!) Loop.
And Lower Loop was the perfect first acclimatising ride at a mere 9,000 feet – was wheezing a bit on day 1! Fine the next day though.
Those local brews sure hit you at altitude 8)
The bouldering at the trailside on Upper Loop looked fun but I'd not taken my stickies with me.
The Andes, Somewhere near the Sacred Valley of the Incas – Probably about 2500-3000 metres. On a hired aluminum Trek hardtail which was rather knackered 😯
40mph.
Which company did you go with? Assume it's Tibet.
I'd have been tempted to have a bit of rear sus' myself on the downhill to make the ride a little smoother.
Went with Exodus (can highly recommend), and yes its tibet. Trails are mostly jeep tracks, a few options to take the fall line down for fun:
Problems are dust and constant stutter bumps where the trucks go up and down – having your head banging up and down for hours when you have a altitude sickness headache is very wearing.
10,000ft at the top of a Jupiter Peak up above Park City UT. Went to the top and back down again from the base at 7000ft 3 times in a day – twice on foot, once by bike IIRC. A few days later we rode to the top again and then went straight from the top down to the bottom (previously we'd gone more roundabout routes) on a high speed straightish run – had some serious brake fade by the bottom. Oh, and that was also at night!
