Mandatory Kit
WHY IS MANDATORY KIT REQUIRED?
Eryri (Snowdonia) is a stunning location for trail-running. However, the weather in upland areas and mountain peaks can change drastically within hours. Even in the month of May the region can experience significant fluctuations of both hot and cold temperatures with heavy rain, hail and even snow forecast!
This creates challenging, and potentially dangerous, conditions if you are not fully prepared. If you are involved in an incident or suffer an injury, your kit (both clothing and equipment) must allow you to remain safe until further assistance arrives. This could be for several hours.
It is essential you carry the mandatory kit required for your competition at all times. Your clothing and equipment must be suitable for all types of conditions and for the duration of your race (i.e. up to two nights outdoors on the mountains for the UTS 100M). We recommend you test using your kit in different weather conditions before arriving at the event to ensure it is suitable for you.
The mandatory kit is a minimum list of essential items required for safety. Participants may add more clothing and equipment to their own list of kit if they feel this will help them while participating in the race and be more comfortable. Participants are strongly encouraged to not approach the mandatory kit list as the only items you need, but instead be proactive and sensible with their kit preparations and decisions.
Your mandatory kit must be with you during the whole race — from start to finish — even if you do not use it. Failure to produce an item of mandatory kit when requested by an event official will result in a penalty or disqualification, including on the start line. For the full list of penalties refer to the Race Regulations.
NEW FOR 2026
The hot weather kit and cold weather kit is now included as part of the mandatory kit check. Participants will need to have these clothing and equipment items and be prepared to present them for inspection at the mandatory kit check before collecting their race bib. Do not leave these items at home.
The event organisers will communicate to participants 24 hours before their race whether any items in the hot weather kit or cold weather kit are no longer required and can be removed (totally or partially) from the mandatory kit list. This decision remains with the event organisers and will be based on the weather forecast and conditions on the course.
Participants must have their mandatory kit with them for the whole duration of the race - even if they do not use it. Failure to produce an item of mandatory kit when requested by an event official at registration or on the course (including the start or finish line) will result in a penalty (i.e. disqualification).
MANDATORY KIT LIST
