Circle the Summit / 7th Annual Bob Guthrie Memorial Ride
Summit County, Colorado
August 16, 2014


The Circle the Summit bike ride is a celebration of the inspirational lifestyle of Bob Guthrie. Past proceeds from this ride were instrumental in completing the path to the top of Swan Mountain at Sapphire Point. The ride is also a celebration of the beautiful cycling options we have in Summit County. Our challenging climbs and magnificent scenery draw the USA Pro-Cycling Challenge back to the area, year after year. Don’t miss your opportunity to experience the same riding as the world’s best cyclists.

The Circle the Summit rides all begin in the Town of Frisco, then circle Lake Dillon before taking off on your choice of four routes. Depending on the route you select, you can cycle south and climb to the top of Ute Pass with rugged views of the Gore Range. Ride east and summit Loveland Pass, with summertime views of Arapahoe Basin Ski Resort. Ride west for great views of the Ten Mile Range and Copper Mountain Ski Resort. Continue on to the top of Vail Pass for splendid views all around, Gore Range, Ten Mile Range and beyond.

Besides the out-of-this-world views, you'll enjoy well-marked routes, incredible aid station snacks, and a delicious after-the-ride lunch – catered by the Historic Mint Steakhouse. Don’t miss out on this year’s event. We cap the ride at 750 riders, so register now and secure your spot on this memorable ride.


We offer four distances ranging from 21 to 100 miles. All of the routes take advantage of the new bike path that circles Lake Dillon.


Where the Money Goes

The Circle the Summit Ride, created by Avalanche Physical Therapy and Summit Biking, has been an influential, private fundraiser to improve cycling in Summit County. Currently there are number of major efforts underway. These include:

By far, the largest effort was the drive to complete a safe bike path around the Dillon Reservoir. Revenue from the early rides helped leverage foundation and government matching grants for completing the Recpath from the intersection of SH 6 and Swan Mountain Road to the Sapphire Point parking area. That section was dedicated on July 15, 2011.

Funds have also financed installation of solar lights in the Vail Pass tunnel and striping on the Recpath through Silverthorne.

Other efforts are underway in Summit County to update and improve existing information kiosks and signage around Dillon Reservoir, including the installation of mile markers, replacement of decking on the bridge across the Snake River, and adding striping on bike lanes to improve safety.
