Ray Mine

Gila Monster 300k

This route forms a loop around the Gila River, and provides scenic desert views through some historic Arizona mining towns. Starting in the Gila River Valley, we pass through Coolidge and then begin a gentle 50-mile 'false flat' climb to Oracle (averaging 1%, with a max around 4%). Oracle is a curios town at the bottom of Mt. Lemmon, so slow down and take a few digital photos. Next is a 33-mile descent into Arizona Mining Country. Pass through Mammoth on the way to Winkelman...then through Kearny, after which there are front seat views of the colorful Ray 'Open Pit' Mine. Next is the 8-mile 'Monster' climb (average 4-5%, with a max grade of 14%). This isn't as hard as it sounds, but better bring a compact or triple crankset if you have concerns. Pass through the mining town of Superior, and then enjoy 37-miles of views of the Superstition Mountains (think 'Arizona Highways' magazine)...home of the legendary 'Lost Dutchman' mine. Following a short out-and-back to the community of Gold Canyon, the route passes through the historic town of Florence before completing the loop in Coolidge.

Total climbing is about 8000 ft., depending on which measurement device you use.

Take note of the route profile as the climbs on this ride are not rollers, but long, steady climbs. The climb that comes at mile 110 will definitely get your attention. It comes in 3 large steps. The last mile is particularly challenging. Remember, walking is just another gear!
