The World’s Toughest 24 Hour – SXS 24-Hour Endurance Challenge.
Invite Only. Limited Entries. No Quit.
The World’s Toughest 24 Hour is an elite off-road endurance challenge designed for those ready to push beyond physical, mental, and mechanical limits. Hosted at the legendary Darkwater Trail System at Famous Reading Outdoors, this 24-hour continuous endurance challenge runs day to night and back again — demanding strategy, resilience, and preparation at every turn.
This is not an open entry event. Participation is limited, selective, and earned.
A Proven Endurance Battlefield
Darkwater is known for its coal-country terrain and relentless trail network, featuring:
- Steep climbs and elevation changes
- Rock shelves and technical trail sections
- Mud, woods, and constantly evolving conditions
It’s the perfect setting for a true endurance challenge where preparation matters as much as performance.
The Ultimate 24-Hour Endurance Test
- Continuous 24-hour operation — no breaks, no resets
- Daylight and nighttime driving requiring full lighting and night-ops readiness
- Strategic pit stops for fuel, maintenance, and driver changes
- Endurance over speed — consistency and reliability win

A small number of 4×4 vehicles will be accepted to further diversify the endurance field.
