10 mile trail run starting at Cache Creek trail head just east of the town of Jackson. Trail runs slightly uphill to the Game Creek turnoff, where it turns to twisting singletrack for 5 miles downhill to the Game Creek trail head. Watch out for mountain bikers on the singletrack, and moose in the willow flats in the Game Creek drainage. Shuttle a car to Game Creek or arrange a pick-up, as it's 7-8 miles back into town on a paved bike path. Beautiful wildflowers, aspen groves, fun rolling dirt singletrack.
