It’s a grueling race with high ridges, technically difficult sections and very limited support. Entrants are required to be excellent navigators even in clag which this part of Snowdonia is susceptible to, vegan for the day at least and extremely experienced fell runners.
Starting at Nant Gwynant as the sun rises the team will first scale Snowdon before going on to climb Crib y Ddysgl and Crib Goch ridge They will then down to Nant Peris for a breather before they head up the torturous Elidir Fawr, and on to Y Garn, Glyder Fawr, Glyder Fach then down the scree and up Tryfan. They will then head back down to Ogwen Valley and their last breather before heading up the wonderful Pen yr Ole Wen, Carnedd Dafydd, Carnedd Llewelyn, Yr Elen, Foel Grach, Foel-fras and Garnedd Gwenllian.
Due to pressure from runners who want to take part but don't fancy Crib Goch or dont have the experience for the ultra, our half takes in the last section across the Carneddau (no nasty drops, only one big ascent, the rest are more gradual).
