Brecon to Cardiff Xtreme 46 mile

The Brecon to Cardiff Xtreme, is the mountain running version of our classic Brecon to Cardiff ultramarathon which is now in its 10th year. The B2C Xtreme is a 73kilometer, linear race over 11 major peaks between Brecon and Cardiff. This is a tough winter ultra marathon with 2650 meters of ascent and is only suitable for those with excellent winter mountain running skills, experience and fitness.

Starting at the canal basin in Brecon the Xtreme heads through the old town then straight to the top of Pen Y Fan – the highest peak in South Britain.  This is followed by steep climbs up Crybin and Fan Y Big, before a fast descent down the Roman road takes you to lower Neuadd reservoir and CP1.  Another short but steep climb reaches the Twyn Mwyalchod trig point, and is followed by a long descent towards Pontsticilli Reservoir and CP2. From here the Xtreme and classic B2C routes briefly converge with some faster forestry running over more rolling hills, before gaining the half way checkpoint in Merthyr.
