MTC CYMRUN : Mount to Coast End to End Challenge

The MTC CYMRUN is a six day end to end of Wales covering a total of 256 miles. The route largely follows Cycle Route 8 and starts at Holyhead on Anglesey, passing Caernarfon, Barmouth, Llanidloes, Glasbury and Merthyr Tydfil before finishing in Barry Island via Cardiff. The organiser added short sections at the start and finish to touch the sea at Holyhead and extend into Barry Island Bay.

Each day forms an individual ultra with its own medal and trophy as part of the Myths & Legends of CYMRUN. Daily distances are:

  • Day 1 : 37.6 miles
  • Day 2 : 50.3 miles
  • Day 3 : 47.2 miles
  • Day 4 : 46.4 miles
  • Day 5 : 39.8 miles
  • Day 6 : 34.9 miles

Accommodation is arranged by the organiser for the ends of Days 1 to 5 on a shared-room basis; competitors arrange their own accommodation before the start and after the finish. Evening meals are included in the race package; breakfasts are provided where possible and may be limited to items such as porridge pots, yoghurt and fruit.

Entrants are limited to 20. Competitors must meet a minimum average pace of 4 mph or be withdrawn, and must carry mandatory kit including backpack, head torch with spare batteries, organiser provided route maps, compass or GPS, whistle, mobile phone and a basic first aid kit. Mapping and GPX downloads and a tracking device with SOS functionality are provided to entrants only. Finishers receive a race trophy, a main CYMRUN medal, six day medals and a bottle of champagne.
