Serpent Trail 50K Info

There are two race starts for the 50k - 8am & 10am.

Realistically for most participants it doesn’t matter which start time they choose; there is ample time from either start to get to the finish inside the cut off of 14 hours and we are happy to have a mix of ability in both start times. But usually the faster runners tend to go in the 10am start.

8am - For those perhaps less confident about doing the distance / making cut offs, wanting a more relaxed experience and looking to have a big day out on this stunning Trail. Ideal for slower participants, walkers and first time Ultra runners. Expected finish time; over 6 / 7 hours.

10am - This start wave will have a mix of ability - but we prefer those aiming to run the route at the faster end of the field, go in the 10am wave. THOUGH ANY TIME RANGE of finisher can go in the 10am start! Expected finish time; 3 - 7 hours.

*The cut off for both races is the same time - midnight. So if for example the 8am time slot is full then by starting at 10am you still have 14 hours to finish - this is how the race always was before the introduction of 2 start times, and is ample time to finish.

There will not be an active waiting list operated for the race so once a time slot is full your only option is to enter the other slot if there is still space. We would encourage you to do this as the later slot is not a hard and fast rule for being a quicker runner, nor is it full of only fast runners!

Route Markings - The whole of the 50k distance is signed with our extra race signage, in addition to the permanent Trail markings as shown below. Below are photos of the temporary race signage and the permanent markers.

We put these extra signs out along the route during the week before the race and they are collected by sweeper runners at the back of the field, then the whole route is ran again by ourselves in the week after the event to make sure we have all the signage collected back in and that litter etc isn’t left from the races.
