How fast do I need to be able to walk/run to reach cut off times?

We aim to cater for all abilities at the event. As a guide, the minimum speed to complete your respective distance is approximately 4km/h or 2.5 mph.

How much training am I expected to do?

This is dependent on how much exercise you do currently. We provide you with comprehensive Training Plans for all distances for both running and walking.

You will also be provided with additional training advice to ensure you are in the best possible shape. Other than that we recommend regular, consistent training – give yourself enough weeks to train but don’t overdo it!

How do I stay safe on the route at night

We recommend that you buddy up if you are on the route at night so you are not walking or running alone.

You should wear a head torch and the signage will be marked with glow sticks to aid night time navigation.

How frequent are the pit stops?

Pit stops are approximately every 10km – 15 km and will give you a chance to refresh and recharge for the next stage and check in with the medics if you need to. We recommend a quick turnaround of a maximum of 20 minutes to get back on the trail as quickly as possible.

All the pit stops provide snacks, drinks, toilets and first aid facilities.

Please note: we do not publish the exact locations of pit stops due to very limited space and private access. In order to gain the necessary permissions to run the event, friends and family will NOT be permitted at pit stops.
