Race Rules

The Rules

1. Categories

  • Solo category – open to male and female
  • Pairs category – open to two male, two female or mixed pairs
  • Teams of Three to Five – all male, all female or mixed sex teams
  • Teams of Six to Eight – this category is only open to mixed sex teams

Once racing begins there can be no change to the team line up. The order in which the runners go on course can change but team members cannot be substituted.

2. Solo Runners

Soloists, obviously, race on their own for the 24 hours. Soloists can take breaks as they require but must only leave and re-join the course at the start /finish arch once they have crossed the timing mats. They should let the timing staff know if they will be off course for more than a few minutes (e.g. if taking a rest period) and also when they resume. Any time off course will be added to their next lap when they continue.

3. Team Runners Handover

Runners can only change over at the designated area at the start/finish zone. When Runner A is out on course, Runner B needs to be ready at the changeover area when A is due to complete his lap(s). Runner A will come in after their lap and hand the exchange baton to runner B before he starts the next lap. If the on course runner intends to run more than one lap they will be able to pass over the timing mats (to register the lap) and continue. If no runner is there to hand over to (e.g. they are still asleep in their tent) the runner on course can either elect to run another lap or to go and find them.

If a runner drops out of your team tell the start/finish staff so they can be struck off the register. Remember your team can’t get a result unless everyone has raced a lap. (This excludes serious injury)

4. Registration

All competitors must sign on with registration before 11:00AM on Saturday. You will collect your race number, timing chip and relay baton at this time. These will not be posted out in advance.

IMPORTANT- runners must check that their details are correct & that they are entered into the correct category when they sign on.

If team members are happy for the Team Captain to sign in on their behalf then he/she can collect the numbers/chips etc. for the whole team

5. Race Numbers

Race numbers must be worn while racing. Please be sure to write your emergency details on the reverse of the race number, include an emergency contact number, any medication you are taking at the time of the event, also any known allergies you have. If a competitor is found on course without their race number on, their lap will be discounted from the race.

6. The Baton

The relay baton must be carried by the ‘on course’ runner at all times. Losing the baton will incur a time penalty with the incoming runner having to wait 5 minutes before being given a new baton to hand over.

7. Race Timing System

FR Systems are again doing the event timing. The system revolves around transponder chips that all runners must wear on their ankle (NOT on the wrist.)

As you pass over the mats at the start/finish arch the system will detect your racing chip and credit you with that lap and time. The clock then starts for the next lap whoever might be doing it. If another member of your team is doing the next lap pass the baton to them, they set off and their lap time will stop when they pass over the timing mats when they return.

Throughout the event screens will be available displaying lap times and positions. If you have any queries regarding your lap times, please report to the timing team immediately, do leave not leave it till later.

8. Minimum Laps

Each registered runner must complete at least one lap during the 24 hours for the teams score to count. There is no maximum number of laps.

If taking a break please leave the course after crossing the timing mats and tell the timing official that you are taking a rest break. This time off course will be added to the next lap when you, or another team member, return to continue

9. Lights

Being a 24 hour race it’s going to get dark and all racers on course between sunset and sunrise must have a working light be it head torch or hand held unit. Bear in mind there will be about nine hours of darkness please make sure your lights are charged and will see you through the whole night. Our lightning sponsors will announce their activities at the event shortly.

10. Finish

The Thunder Run 24 hour officially finishes at 12 noon on Sunday. So long as a runner starts a lap before the 24 hours have elapsed that lap will count in their total lap score once completed. Teams can declare at any point (if all team members have run one lap) and their total laps completed will still stand.

The winning team will be the one that completes the most laps in the shortest time. Results will be as number of laps plus time taken to finish after 12:00PM and might look like this:

  • 1 - Team A 13 laps; 24:02:00
  • 2 - Team B 13 laps; 24:15:00
  • 3 - Team C 12 laps; 23:01:00

Team A wins with 13 laps and a finish time of 12:02PM; Team B come in next with 13 laps finishing at 12:15PM; Team C have less laps so come in third even though they decided to finish at 11:01PM.

11. Results
The provisional results will be posted online as soon as possible after the completion of the race for everyone to review. Should you find any issues please email the timing team on thunderrun@frsystems.co.uk with the details of your query and include your bib number.

They will look into it and adjust the results if necessary. All queries must be made by close of play on the Wednesday, 24th July 2019.

12. Cheating

Cheating will not be tolerated. Substituting unregistered runners, cutting through the tapes, taking short cuts and any other cheating will result in instant disqualification of the runner (if a soloist) or the complete team.

13. Quiet Time

Between 11:00PM and 07:00AM please keep the noise on the campsite to a minimum. Please consider everyone on site.

14. Medical and Massage

There will be a qualified medical team on site to deal with medical emergencies for the duration of the event. The First Aid point will be stationed in the main arena. All race marshals will be able to radio for help if necessary.

Masseurs will be in attendance. These guys are all volunteers and will massage competitors for a cash donation. Please turn up with clean legs and bring your own towel.

15. Problems During the Race

If you have any problems while actually racing or encounter a fellow competitor having problems please tell the next race marshal so assistance can be called if required. Similarly, if you encounter people messing with course markings or lurking around looking shifty, tell a race marshal and they will ask an official or security to investigate.

16. Headphones

Ideally, we would prefer you not to use headphones whilst running, but due to the duration and nature of the event runners are permitted to compete with one earphone in only. Runners found to have two earphones in will be subject to a time penalty or have their lap discounted, at the discretion of the event directors.

For 2019 we are permitting the use of bone conducting headphones on a continued trial basis. The organisers reserve the right to withdraw the use of these if any issue arise.

17. Post Event

We recommend that you take Monday off, sleep in, rest up and eat lots of nice food.
Don’t travel too far on Sunday night if you can help it, or get a fresh driver to take you home. 

Hints and Tips

Team Mates

The guys and girls you’ll be running with and sharing the experience with are vitally important to you. Make sure that everyone in the team has the same kind of goal in mind. If one of the team has their heart set on winning outright whereas the rest of the team would be over the moon just to complete the distance, then friction is bound to occur. Make sure that you are all ‘singing off the same hymn sheet’ and your race will run a lot smoother.


You, your team mates and helpers are encouraged to set up camp the night before the race. This will give you plenty of time to get organised. On the day of the race you’ll soon be busy with the running itself so anything you can get prepared in advance is a bonus


You’re going to burn off a lot of calories over the duration of the event so making sure you are fully fuelled is imperative to success. We will have caterers on site who will be open night & day preparing hot & cold food but self-sufficiency is a good thing. There’s no queue for one thing. Bear in mind that you won’t want anything that’s too complicated to make.
Your time off course is precious & you’ll want to spend as much of it as possible resting up. If possible, call on a friend or partner to be your chef for the weekend to take care of the food. Remember to keep hydrated at all times too. If you’re not used to energy drinks this isn’t the time to start experimenting with them. Stick to what you are used to.


Take as many changes of clothes as possible. It doesn’t matter if the weather is good or bad there’s nothing quite as demoralising as having to pull back on cold, wet kit. Likewise, bring more than one choice of footwear.

The Race

Remember how long the race is. Don’t go out like a bat out of hell and end up in a withered heap after the first couple of laps. Pace yourself, learn the course, it is quite technical out there so having good knowledge of what’s around the corner is valuable.

Change Over

To see out the duration without any hitches good timing at the changeover is key. It is worth finding a willing volunteer to help with the timing & making sure everyone is woken up at the right time & at the changeover area on schedule. Keep track of roughly how long everyone in the team takes to complete a lap, write things down & have a clock handy to work out the approximate hand over times. That way the runners get as much rest as they can & spend as little time as possible standing around waiting at the change-over area.

Hours of Darkness

For many competitors this will be their first experience of running off-road in darkness. It adds a new dimension to the competition & should be treated with respect. Get a good light, test it & have a back-up in case of emergencies.
