Terrapin Southeastern Endurance Series 6/3 Hour MTB Race Rules and Regulations

Racers can only compete with one number plate on the bike at one time. A racer cannot compete in simultaneous categories ( for example, 3 Hour Expert and 3 Hour Single Speed). A racer can, however, compete in one 3 Hour Solo and then transition to one 6 Hour Team. If this occurs, laps for 6 Hour Team must be scored under the team plate ONLY. In other words, solo laps will NOT count towards team lap total.

All teams must consist of the same people to qualify for series points. If a team needs to add a substitute racer, a new team name will be given for that race and the team will be scored under new team name. That race(s) will not count towards Series Points.

Race Age is your age on December 31 of that year. Junior Teams are 16 and under.

If the race is canceled due to inclement weather, the points for that race will be made up at the series finale. If you were registered for a race that was canceled due to inclement weather, you must register for the series finale and complete a minimum of 1 lap in the series finale to receive points for the canceled race. The points for the series finale will be awarded using our regular points scoring system. We will then take your score from the series finale and double it to account for the canceled race.

If an issue occurs on the course regarding unsportsmanlike in the race (blocking or unsafe racing), those issues must be brought to the attention of the race director. The race director will absolve all issues related to unsportsmanlike on the course. If the issue is with a junior racer, then at NO POINT will it be tolerated for an adult to address the issue with the junior racer. It must be addresses with the race director and the parent or coach associated with the junior racer.

The 6 Hour Mountain Bike Race will start at 10:00AM. Your bike should be positioned at the starting line no later than 9:45AM.

The first team member starts at 10:00AM. Junior teams start at 10:00AM.

The 3 Hour Mountain Bike Race (all categories and ages, including juniors competing in 3 Hour categories) will start at 10:15AM. Your bike should be positioned at the starting line no later than 10:05AM.

The Junior 1 and Junior 2 categories will start at 10:20AM. Your bike should be positioned at the starting line no later than 10:10AM.

There will be a mass start of all race categories at one time. Please line up with Experts on the first row followed by Single Speed, Sport and finally Base and Beginner categories.

As you finish each lap, please continue all the way through timing (at the Maxxis arch) and then you may stop in your pit area. Please plan accordingly if you plan to stop and position yourself on the course so that you will not have to cut from one side of the course to the other in order to get to your pit. Please do not stop in front of timing. Continue through and then come back to timing without your bike if you have a question.

Each racer must have the number plate mounted and visible on the front of the bike.  Please use at least three twist ties to secure your plate and make sure you place is facing outward, not upward. Please do not cut your plate down as we need to be able to see all the numbers for our back up timing system. Number plates will be provided at the first race of the series that a racer participates in. That same number plate will be used throughout the series and it is the racer’s responsibility to bring that number plate to all races that they participate in. Additional number plates will be issued at a replacement cost of $10. Partner races (such as Dirty Spokes) have their own race plates.

Please do not use a plate from a different race company or different series.  24/12 Hours of Tannehill/The Iron Maiden has its own plate.

6000 – 6 Hour Solo

200 – 2 Person Team

300 – 3 Person Team

3000 – 3 Hour Solo

Once you cross through the timing area you may continue back out on the course or teams may transition from the TORQ transition area. Once a team member has visibly come through time (at the Maxxis arch), the next team member can take off from transition.


If you or a teammate has a mechanical out on the course there are couple of options.

  1. Fix your mechanical as quickly as you can and get riding again. You don’t have to be self-supportive in this race. If another rider comes along and they have a tool or knowledge to help,  they may do so.
  2. If a (TEAM) rider that has a mechanical or has a wreck preventing them from finishing the lap, the rider can radio or call in to their team to send another team member on course to start a new lap. The new rider must check in at the timing tent before entering on course. Once a racer radios or calls in and reports to CANCEL the lap, it is CANCELLED. No exceptions.

Racers may ride as many laps consecutively as they wish. Each team member must ride a minimum of 1 lap during the 6 hour period. All laps must be completed by 4:00 PM or they will NOT count. The 6 hour race winners will be the ones that have tallied the most laps at the end of the 6 hours in the fastest time.
