Please visit our withdrawals page to make a withdrawal request.

Can I give my entry to a friend?
No, please follow our withdrawals process if you can no longer run a race.

After entering a race, what should I expect?
You will receive a confirmation email from us and a payment receipt from Stripe. This can sometimes take a few minutes to arrive and may end up in your junk folder.

As the event gets closer we will send you race relevant resources via email. We won't send you anything in the post.

How do I navigate the race route?
The primary form of navigation for all our races is via orange arrow markers and ribbons. Additionally, there will be several marshals at busier/confusing locations.

For our 50km races, you are required to carry a paper map (provided at registration), or have access to the GPS track on your phone or watch, just in case you need it as a backup.

What happens if I get lost?
Retrace your steps, looking out for a left/right turn that you may have missed.

If you have the GPS track on your watch or phone or are carrying a route map, consult this to help find the correct path.

If this fails, please call the event phone number.

Sometimes signage gets tampered with, if you think this is the case please alert the race director via the event phone number.

Remember, successfully navigating yourself around the route, is part of the challenge in a trail race, keep your head up and look out for signs at all times.

Can I listen to music during the race?
Yes, headphones are permitted, however, they must be removed at the start, when at checkpoints and at any road crossings.

Will there be toilets available on the route?
Most of our checkpoints have toilets, however, please check the specific race information to be sure.

What kit is mandatory?
Please check the 'Required gear' section on your specific race page.

Are pacers allowed?

How are road crossings navigated on the course?
Runners are responsible for their own safety while crossing roads, and if necessary they will need to stop to allow traffic to pass. We aim to have marshals at all busy road crossings to aid the safe crossing.

What happens if I'm injured or need to withdraw during the race?
In the first instance, please make your way to the nearest checkpoint, or walk back to a marshal (if you have recently passed one).

If you are unable to do this, and your injury is not life-threatening, please call the event phone number (provided in the race-specific communication).

In order to locate yourself and communicate this to us, we recommend having the OS Locate application downloaded to your phone.

In the event of a life-threatening injury, please do not hesitate to call the emergency services and then alert our event team.

Please return your timing wristband to a marshal before leaving the race
