A deliberately absurd ~160km (100mi) 'not-a-race' gravel adventure in Bakersfield, California — ranch obstacles, hike-a-bike and creek crossings, where the terrain (not the ~1,500m of climbing) is the difficulty. Date approximate (est. mid-Feb 2027).
A gravel day that insists it is not a race. Roughly 160km through the ranch country around Bakersfield, California, stitched from dirt roads, singletrack, creek crossings and deliberately silly hike-a-bike obstacles.
The ~1,500m of climbing badly undersells it. The difficulty is the terrain: constant surface changes, off-bike scrambles and wet feet, with no rhythm to settle into over a hundred-mile day.
It's a February cult event, timed but built around survival with a smile. Ride it as an adventure and the absurdity is the joy. Race it and the terrain will wreck you.

Is Rock Cobbler for you?
- Riders who want an adventure over a result. It's timed but not a race, and it rewards patience and humour far more than raw power.
- Confident off-road handlers. The surface never settles, so it suits riders comfortable on loose, steep and wet ground.
- Long-day diesels who keep eating. Eight to ten hours of broken-up terrain rewards steady fuelling over early aggression.
- Anyone happy to get off and hike. The obstacle and hike-a-bike sections are unavoidable, so carrying the bike is just part of the day.
Training plan for Rock Cobbler
A training plan for Rock Cobbler isn't a generic base build. Beina reads the event's exact demands, looks at your specific profile and the time you actually have, and maps a highly adapted plan to the start line.
- Constant surface changes: gravel, singletrack, ranch dirt and loose steep pitches with no rhythm to settle into.
- Hike-a-bike and ranch obstacle sections that put you off the bike, carrying and scrambling.
- Creek crossings that leave you with wet, cold feet and slick remounts.
- Eight to ten hours or more of never-settling terrain, where mental grit matters as much as fitness.
- A progressive long ride building from 3hr up to a 6-8hr mixed-terrain day, the core adaptation.
- Chaos simulation rides on the roughest terrain you can find, including deliberate off-bike sections.
- Steep-pitch strength: low-cadence seated efforts on loose climbs, plus hike-a-bike drills.
- Mixed-terrain handling and creek-crossing remount practice, with fuelling rehearsed at 60-90g carbs an hour.
- Built from your current fitness and the time you actually have
- Adapts every week as Beina learns how you respond
- Syncs your sessions straight to Garmin and Wahoo
- One clear next session, never a wall of spreadsheet
