Three Creeks
BIG GRIDER
92 Miles – 7448 Feet Elevation
Percentage of Gravel 91%
Ride with GPS Map https://ridewithgps.com/routes/40935972
Course Description: Three Creeks Gravel Race will throw everything at riders. Big climbs, fast descents, super smooth cinder, chunky rock, sand, and expansive views of the Cascade Mountains will keep everyone’s attention from the start to the very end. Two big climbs in the first 35 miles of the race will help create separation and provide a test to everyone’s fitness. Climbers will have the advantage however with 67 miles of racing left the race will be far from over. Shorter power climbs, technical sections, and possibly winds will create many challenges on the day. Once again the beloved “4 Miles of Hell” will return. Pay attention on this section and falling will hurt with large rocks everywhere.
