Schwalbe G-One Overland is the ideal tire for Cascade Gravel Grinder because it strikes the perfect balance between speed and grip, allowing riders to tackle a wide range of terrain with confidence. With sturdy construction and excellent puncture protection, these tires will keep you rolling smoothly and reliably throughout the event. Available in 700x40/45/50 you can select the perfect size to fit your riding style.

 

If possible, choose a 700x40c tire for the smooth and fast courses on Friday and Saturday.  The rugged terrain on Sunday’s course would be best suited by a higher volume tire in the 700x45c range.

SUNDAY- Three Creeks

BIG GRINDER- UPDATED COURSE

Ride Distance 82.2 mi 

Total Gravel 90%
Total Elevation 6622 ft

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.  

 

MEDIUM GRINDER

Ride Distance 60.5 mi

Total Gravel 55%
Total Elevation 4335
 ft

Ride with GPS Map  https://ridewithgps.com/routes/40936106

Course Description:  Medium Grinder will send riders up the paved Three Creeks Road for the first 9 miles.  After that it is nearly all gravel.  One big climb at the start and then a lot of rolling terrain to the finish.  Unlike the Big Grinder you will enjoy a lot of smooth solid gravel from start to finish.  Massive views of the Three Sister’s, Mt. Jefferson, and Mt. Washington will take your breath away.

Ride Distance 42.7 mi

Total Gravel 77%
