Got the Avid Climber. Have climbed AdZ 10 times so far, and am at 49% (80,389 ft). Currently need to climb it nearly 27 more times for the Tron bike!! Pity I didn’t default this challenge as the first one when I started going through the routes, as it was the latter ones with the greater elevation gains that helped. Had I known about this in the beginning, I could have been chipping away at increasing the climbed height at an earlier occasion!
Oh well, never mind! Will have to look forward to a lot more AdZ climbs yet!!!
