2025 Reroute Rider Guide and Segment Challenge Details

The complete 2025 GWR Rider Guide just dropped, revealing everything you need to know about San Diego's most talked-about gravel adventure. This year marks a first: two course options. The classic 70-mile route with 7,500 feet of climbing remains the full GWR experience, while the new 45-mile Short Course opens the door for more riders to taste the legendary Viejas Grade gravel and Cuyamaca's singletrack.

Key details now available include precise aid station locations powered by Mammoth Tuff, mechanical support points from Velofix San Diego East, and the brand-new Ride with GPS Segment Challenge featuring three timed gravel segments with prizes from Holland Cycles.

The semi-supported format strikes a unique balance—strategic aid and mechanical support where you need it most, but you're still responsible for navigation and self-sufficiency between stops. Finish festivities at Mike Hess Brewing include Freak Shake recovery drinks, a rider feast, and prize drawings from Topo Designs.

Routes are unmarked and GPS navigation is mandatory. The guide includes critical POIs, safety warnings, and detailed preparation requirements. With just a handful of spots remaining and the event less than a week away, the full Rider Guide should answer all remaining questions.
