Weekend Option: Test your endurance and cardio capacity this Saturday with the I Think I CANyons bike ride - a.k.a Utah's most intense road cycling ride.

The ride benefits the Fourth Street Clinic, providing high-quality and respectful healthcare for the homeless. 100% of the proceeds go directly to the foundation.

Dets on the ride: You have two options: #1) The original challenge - a 110 mile ride through 4 canyons. The ride starts at the Olympus Hills Shopping Center (3900 S. Wasatch Blvd.). From there you'll ride south to Little Cottonwood Canyon, followed by Big Cottonwood, Millcreek and Emigration Canyon. The elevation ranges from 4946 ft. (the starting point) to 8526 ft. (Big Cottonwood) so this is NOT for the faint of heart (Yes, that's 12,00 vertical feet). If you manage to survive the challenge you'll be rewarded with a free Barbacoa burrito. Totally worth it, believe me.

Option #2) The second challenge (for those of you who'd rather not attempt to explode your heart/legs) also begins at the Olympus Hills Shopping Center. This round only climbs Emigration and Millcreek Canyon in a mere (pffft) 43 mile trek. The highest elevation reaches 7454 ft in Millcreek and you too will be rewarded with a free Barbacoa lunch in refueling attempts.

Oh - yes, there will be water and aid stations at the top of each canyon.

The History: The inaugral race begin in September 2007 after 6 college friends completed an epic 1,000 mile ride from Seattle to SF in 2006 for homelessness. The ride inspired them to do so in SL, resulting in the first annual I Think I CANyons ride. Each year, the ride garners more riders and attention and, as a result, the Friends of Fourth Street have raised more than $15,000 for the Fourth Street Clinic.

The Registration: The ride begins at 6:30 a.m., Saturday, July 16th at the Olympus Hill Shopping Center, registration/check-in starts at 5:45 a.m.

The 4-canyon ride costs $45 to register, the 2-canyon ride is only $35. You can register here online.
