Alta Alpina Challenge


8 Pass Challenge

"The World's Toughest Double Century"

The course features nine fully stocked rest stops, two checkpoints with water, and lunch and dinner at Turtle Rock Park.
There will be a bag drop to the top of monitor for lights and warm clothing (both required after 8:58pm). You can bag your items at the start or when you get to the top of Kingsbury.
Each rest stop has opening and closing times that must be respected and checkpoints will strictly enforce cut-off times intended to keep everyone safe.
This is the ultimate one day challenge and is for riders physically and mentally prepared for this adventure.
An exclusive 8 Pass Finisher Jersey will be available for purchase to those who complete all eight passes.

The Grand Tour and Alta Alpina 8 Pass Challenge are both scheduled for the same date. If you are a California Triple Crown participant and wish to ride both events we can accommodate you in our staff ride. Please contact for details.
