Cycling stops in Tucson & the Sky Islands

Tucson's reputation rests on one road. The Catalina Highway leaves the eastern edge of town at saguaro height and climbs for about forty kilometres to Ski Valley, gaining the better part of 1,800 metres and passing out of the Sonoran Desert into pine forest on the way, a change of vegetation that would otherwise take a drive to Canada. Riders stack up at Le Buzz at the bottom before the climb and at the Cookie Cabin in Summerhaven after it, which is as close as American road cycling gets to a liturgy.

The rest of the riding fans out from there: Gates Pass and the Saguaro West loop to the desert museum, the long straight run south past the Titan silo to Madera Canyon, Kitt Peak's observatory road out on the Tohono O'odham Nation, and the mission of San Xavier del Bac standing white against the desert on the way home. Two hours east, Mount Graham's Swift Trail climbs 34 km into the Pinaleños, the biggest of the sky islands and the region's longest sustained climb. It stays rideable through the winter, which is why the training camps come.
