Vegetarian and vegan refreshments will be available. We’ll also have a Medic, First Responder or a First Aider available at each CP.
There are strictly enforced cut-off times per Checkpoint implemented by the Event Organisers, to ensure a safe event.  Checkpoint distances are approximate and may vary each year should there be minor diversions on the route (due to local authority/landowner works).  You must enter the checkpoint before the cut off time to proceed further in the event.  Should you pass through the Checkpoint in time, you may stay at the relevant checkpoint for no more than 20 minutes after the cut off.
Participants must attend ALL checkpoints and have their details recorded by the Checkpoint teams. Failure to check-in at a Checkpoint will result in your disqualification from the race.

50 Km participants – All finishers will automatically receive a Finisher’s T-Shirt.

10 Km & 5 Km participants – T-Shirts are not included by default. If you’d like one, please pre-order during registration.

The results will be available real-time during the event and we’ll update this page with the link prior to the event.
As each runner crosses the finish line, their race chip records their individual finishing position and finishing time.
Your position and time shown in the results link is your official result. Please note that the tracking system is different to the timing system and has no bearing on your chip time or result.

We’ll be posting the links to the official media team photographs here after the race has finished.  Please keep checking back to find yours.
Processing and editing the photographs does take some time so please allow 48-72 after conclusion of the race for the links to be added.
We’ll also be adding photographs taken by the event team on our K2xtreme ultra Instagram page!
