Event overview
Come and join in the fun - distances for everyone to get involved!
Whether you’re an experienced runner or a newbie trail runner, TrailFest is for you!

The idea of the day is to bring everyone together to experience the fun of trail running in an amazing forest.
Being around others doing what seems impossible can often make it seem a lot more possible too! If you want to come and run your personal best or bimble about with your mates this is for you.
This event is part of TrailFest | Salcey Forest.

The key thing is that these events are for everyone. There is no such thing as too slow!
Dogs
As the event is run under a UK Athletics/Trail Running Association license there are no dogs allowed.
Support team
You can have crew, they’re really helpful for longer events but you cannot have pacers. To be clear, that means no-one can run with you or walk alongside you for any period of time except in the final 100m or so.
Spectators and supporters are encouraged but they must not move along the trail with you. They can pop up all over the course though - or just stay in the cafe all day!
There is a large grass area near the HQ that can be used to put a gazebo up if your team, club, or supporters wish to. This must be pre-arranged.

Overview
The different routes all use similar sections of the forest. The majority of the routes are along well-maintained pathways. There isn't a meter of asphalt (except at 2 road crossings for the longer events!), and the pathways are mainly crushed stone or very well-trodden open forest floor.
The previous editions of this event have been in mid-spring, we’ve moved to the summer to give a “better” underfoot experience - no trench foot hopefully in June! If it’s been raining, the ground may be soft as there are sections of grassland. Expect a hard-packed trail for the vast majority of the route, however. Watch the video for full details.
If the weather has been typical of the season, you could run this event in road shoes, although a light trail shoe is probably ideal given the uneven stony surface that covers most of the route. Personal choice of course!
Cut off
7pm.
For the 50km event, that means an 11-hour cut-off - 21min/mile pace.
All other events have the same 19:00 cut-off, so that’s 10 hours to do the 10K!

The route was very well marked and the volunteers at the stations were amazing and lots of snack and drinks to choose from. Judith
My first 50K. A great event with the perfect mix of feeling alone in a beautiful forest with great aid stations and supportive marshals. Even the mud was not enough to dampen spirits, it’s a trail event afterall. Simon T
A huge thank you to all of the organisers involved in making this event happen. The marshalls were friendly and supportive. Aid stations very well stocked. Really enjoyed the whole thing despite the appalling weather and muddy conditions! Paul did brilliantly to give us required information in advance and made us all feel relaxed on the day. Delighted to have completed my first ultramarathon here! Holly G
The Salcey 50 was such a fabulous day out. The first thing to mention in my review is the wonderful volunteers - the tambourine cheer squad at the on course aid station was just magic, there was all the encouragement and support wherever you looked.. Thanks Big Bear for helping me achieve my goals! Kaz K
