To enter you must first Log In or Register your Details with SiEntries.

Starting at the base of the Mountain, a harsh and brutal climb up to the first leg of the Table. Skirting the perimeter, you will collect a wrist band before facing the steep south face who will be smiling down at you at you. The outstanding views stretching as far as Pen Y Fan will make the climb worth while. Continuing your fight traversing some technical paths, your aim is the summit of Pen Cerrig-calch at a height of 701m before claiming victory and collecting your second wrist band. Full of light relief you will then have the chance to pick up some speed and marvel at the very fast but tricky descent back past the Table Mountain and back to base where you will hand in your bands and then decide whether to head straight back out or to rest and enjoy some light relief and refreshments. Our team of physios will be on hand for any aching muscles that may need some attention before taking on the next challenging and testing loop. A strict 10hr cut off will be in place- any participant that does not reach base before the final horn will not have that loop recorded, this only adds to the challenge to ensure you are fast enough to beat that horn! 

Team entries will be a collective number of loops, even if a team player drops out. Last man standing approach - Teams must be named.

Base will try and ensure that there is adequate space for support crews however please car share if at all possible.

Strict rules will apply - any runner whom the medics deem unable to carry on will only continue so at their own risk. The event organisers will take no responsibility for such actions.

Come along and Conquer the Mountain.
