The marshals are local and also supported by experienced Ultra Runners.

The last section from Cae Corn Mawr to Plas Heli will be well supported with marshals, as it will be dark and you may be a tad fatigued by then! This is also a section where if you have any friends and family coming to support will be an idea to suggest to them to be as a smiley face will im sure be more than welcomed.

There are many places along the route to support and cheer the runners and provide aid. Our check points will have fluids, gels and snacks, however, additional food and fluids can be provided by helpers anywhere along the route. Note that some sections of the route are long and arduous with some considerable time between aid stations - so be prepared and ensure you carry enough supplies.
