Rocky Hill Ranch, Smithville, Texas
9:00 a.m. (all races!)
A 24-hour mountain bike race that can be done solo or on a team of up to 10 people. This is a 10(+-) mile course. Teams try to log as many laps as possible, with only 1 member riding at a time. The team or solo rider with the most laps in the 24 hour time period wins. The single track winds through oak and pine groves combining quick up & down hills, short technical sections, and fast flowing trail. The course is marked with arrows for day riding, reflective tape for night riding.

Right to Cancel or Reschedule – Terra Firma Racing LLC reserves the right in the event of inclement weather, emergency, or natural disaster to cancel the race or move to a later time that day or alternate date within the year (if available). In the event of a CANCELLATION with no ability to reschedule, there will be NO REFUND OF ENTRY FEES. Each athlete must accept any such risk for their entry paid. That said, we have never had to cancel the DIRTY DOZEN MOUNTAIN BIKE RACE yet. We even had snow one year. We did have to shorten the course to 8 hours instead of 12 though.
