Extra details
Clockwise route this year. Full kit and good navigational skills required. You will need to demonstrate sufficient fell running and navigational competency as a condition of entry. Some details tbc.

The race includes 4 checkpoints which must be visited in the correct order, namely:

CP1 - Fan Frynych trig point, GR SN 958228
CP2 - Fan Nedd trig point, GR SN 913184
CP3 - Fan Llia (true) summit which is almost entirely unmarked, GR SN 938186
CP4 - Fan Fawr cairn, (not the trig point) GR SN 969193

There will probably be a cut off at Fan Nedd. Competitors will be compulsorily retired from the race if they do not make this time. So, please be sure you can achieve this (and then of course finish the remainder of the race safely). We should be able to accommodate an early start (tbc) for those who are slower than average (but have appropriate fellrunning experience).

Location

Lay-by opposite Storey Arms, LD3 8NL on A470 between Merthyr and Brecon (GR 983203)

Safety information

The route is entirely unmarked with a significant amount of route choice across surprisingly remote terrain. Whilst there are paths, most of the climbs and descents are off-piste so self-reliance, good navigational and sound mountain judgement is required. There are a couple of river crossings so competitors must carefully choose a safe crossing point – occasionally rivers are in spate so please consider heading up stream. Similarly you will need to cross and re-cross a mountain road - take care. In good weather the course is relatively benign but in limited visibility good map and compass skills will be required. You may use GPS for route finding but please let the RO know on the day so that you may be recorded as ‘non-competitive’. Respect the natural environment and the landowners by staying clear of livestock, not climbing any wall or fence, (use the stiles). Failure to do so will result in disqualification. Please note the cut-off times at the checkpoints and if you doubt your abilities contact the RO before entering as all competitors will be vetted on the day. Bring full kit to the race (including waterproofs) as in previous years these have been required far too often.
