Penllyn Ultras 2024 Rules

Support Crews

Please provide all the names, and contact details of your support crew to at least 4 weeks in advance. 100-mile competitors must have a support crew until CP1.

Support crew for the 100 are not allowed at CP1 in case a competitor mistakes them for the event crew and please ensure your support crew does not get in the way of the event team, volunteers, and competitors along the courses.

100/75 Support runners are allowed from Y Ffic Llithfaen only. 50 support runners are allowed from the Water station at Cae Corn Mawr.
You must notify at least 4 weeks before the event with the support runner’s name and contact details. Support runners are not allowed to carry any item of kit for a competitor. Failure to do this will result in a DNF. No support runners are allowed before these locations.

Mandatory kit

Competitors must carry this at all times. There is a kit check at registration. Spot checks on the beach before the start and random bag checks at Aid Stations. Removal from race if your mandatory kit isn’t complete. This is for your safety and the safety of the event team.


BIB numbers must be worn on the front of your T-shirt or Shorts and if you put a jacket on top of a t-shirt, the BIB is placed on the front of the jacket. No BIB numbers are allowed on your back. You will be removed from the race if this is not done. This is for your safety and for quick reference in case of emergencies.


This must be worn on your bag strap facing the sky. Do not put it in your bag. We have an event team tracking the competitors and if we require swift access to attend to a competitor the correct positioning of the tracker on the competitor is paramount. You will be removed from the race if the tracker is not on your bag.

Winter Ultra

For the Winter Ultra there are strictly no pacers or support runners allowed on the course. This is to ensure a fair race for all competitors.
