Training advice
Local trail running site Running for the Hills have an article with advice on training for a hilly ultra, using the BTU50M as their example target race. The site also has lots of other advice on trail running in general and gear.
Navigation:
The races are self-navigation and competitors must either carry paper maps (these are available to download and print on the Routes page), or two suitable electronic device (see kit list below) at all times. The Butcombe Trail itself is waymarked along much of its length but this can be patchy; we divert from the official trail in a few places, and the BTU50k follows a different route for part. There will be marshals at key points and a small number of race markings to help. GPX files of the routes are available on the Routes page. These are updated regularly so always make sure you have the latest version.
Feel free to get out on the course before race day to check out the route. It’s a beautiful course on public footpaths and there are plenty of lovely Butcombe country pubs on the route. If you visit one of the pubs on a recce, please be sure to mention the race. There are details of all the pubs and suggested recce routes here.
Entry Requirements:
Although runners will be well supported during the event, it is not to be taken lightly.
For the 50 mile race only runners who will have run a trail marathon by race date (either as a race or in training) since 1 January 2025 should apply.
For the 50 km race we do not require this but you should neverthelsss be confident you can run this distance self-navigated.
Entrants must be at least 20 years of age.
Headphones
Headphones are not prohibited on the Butcombe Trail Ultra, however we encourage runners to avoid using them and to enjoy the sounds of nature and chat with fellow runners. If you decline to follow this advice, this is your responsibility. Note that you must be alert to instructions from marshals, the risks of road sections and crossings, and the needs of fellow runners at all times. This is for the safety of yourself and others. Both earpieces MUST be removed at all checkpoints and marshalled road crossings, runners risk disqualification if they do not follow this requirement.
Mandatory kit list
Runners will need to carry minimum kit of:
- Water bottle or bladder (it is up to 10 miles / 16km between checkpoints).
- Cup (optional, but will be needed if you want a checkpoint drink served other than in your water container (e.g. coke or squash).
- Whistle.
- Waterproof top with hood and taped seams.
- Waterproof or windproof trousers.
- Long sleeved warmer top layer.
- Fully charged mobile phone with volume set to maximum.
- Gloves.
- Buff or hat.
- Emergency food (e.g. gel, energy bar).
- Headtorch with charged batteries (50 mile only).
- Survival bag or emergency foil blanket.
- Either:
- paper maps of the course, to be carried at all times – YOU MUST BRING YOUR OWN – either download the GPX files provided and print via your chosen app, or obtain the relevant OS sheets marked-up with the route. These must either be on waterproof paper, or in a waterproof case / sleeves.
OR - TWO independent electronic devices (e.g. GPS watch and smartphone), with sufficient battery to last for the full duration of the race (15 hours). You must carry a spare battery if necessary to achieve this.
- paper maps of the course, to be carried at all times – YOU MUST BRING YOUR OWN – either download the GPX files provided and print via your chosen app, or obtain the relevant OS sheets marked-up with the route. These must either be on waterproof paper, or in a waterproof case / sleeves.
- Compass (not required if you are using two electronic devices as above, both of which include GPS/compass functionality).
- Sunblock or additional warm clothes as dictated by weather conditions (at your own discretion).
We recommend that runners wear trail running shoes with good grip.
Depending on weather conditions, we may waive one or more items on the day, but you must arrive at registration with everything on the above list.
Checkpoints:
There will be seven checkpoints on the 50 mile route, three on the 50 kilometer. Many of these are at Butcombe pubs and village halls. You must visit every checkpoint. A variety of sweet food (e.g. cake, biscuits, fruit, sweets, malt loaf), savoury food (e.g. crisps, nuts, sausage rolls), water, squash, and flat cola will be available at these checkpoints. You can also buy good local beer and cider in the pubs!
Please attach your race number to your front so that it can be clearly seen. You must show this number to marshals at each checkpoint – it is your responsibility to ensure that your number has been noted. You must not run with another person’s number.
The variety of food available should mean that if you have a minor food intolerance there will still be items available at each checkpoint to suit. However, due to the nature of race checkpoints, we cannot guarantee that there is no possibility of contamination between items. Therefore if you have a sensitive allergy we would ask you to provide us with sealed, named bags, numbered for each checkpoint; these may contain an appropriate amount of nutrition items, but cannot be used for other equipment. Please email us in advance if you wish to do this as we have to arrange exchange of the bags.
There will be a free hot meal at the end of the race for all entrants (vegan option available).
Drop Bags:
There are no provisions for drop bags in either race. However, in the spirit of the event, we would encourage runners to be semi self-sufficient and carry everything they intend to carry for the entire race. In any case, the mandatory kit list must be carried at all times (for example, it is not acceptable to pick up your head torch half-way).
The only exception to this is in the case of genuine medical needs for specific food items (see ‘checkpoints’ above).
External support:
Runners are welcome to have their friends meet them at checkpoints and it is permitted to exchange items, however, the full kit list must be carried at all times. Supporters may accompany you for a short distance into / out of each checkpoint, providing this doesn’t hinder other runners. Supplies must not be exchanged other than at the checkpoint locations, in-keeping with the principle of self-sufficiency.
‘Pacers’ (friends) are allowed to run with you only after the final checkpoint (CP7, Beacon Batch). All self sufficiency rules must still be followed – i.e. carry all kit and do not receive any supplies.
Cut-off times:
There is a maximum time of 15 hours to complete the 50 mile race finishing at 11pm and 10 hours ending at 7pm for the 50-kilometre.
The following intermediate cut-offs will be enforced for both races:
NOTE: There is NO VEHICLE ACCESS for spectators to CP7 the Wireless Station at Rains Batch because it is at the end of a single track lane and must be kept clear at all times. If you wish to see runners there is limited parking along Ubley Warren Drive and Blackmoor Reserve car park BS40 7XR. Please respect the local community and park responsibly or it may compromise our permissions to hold the event in future years. Thank you.
Providing runners make it through the last checkpoint within cutoff, they will still be counted as finishers and earn their UTMB index, even if they miss the overall time limit. If any of the checkpoint cutoffs is missed, the race number must be forfeited and the runner will be counted as DNF.
Prizes:
All finishers will receive a bespoke medal, which is specific to each edition of the race.
There will be awards for 1st, 2nd, and 3rd male and female in each distance, as well as various spot prizes and other goodies.
Camping:
Please see our dedicated camping page
Parking at the start:
Plentiful parking will be available at The Mendip Activity Centre.
Running with dogs (Canicross):
Since the race moved to April, we regret we can no longer accept runners with dogs due to the large number of lambs, calves and other young livestock present in fields throughout the route.
