Back for its sixth year!
Come and take on the Table Mountain in the Black Mountains of Wales. The 10 hour 4-mile strenuous and technical loop race is a test of endurance and determination. This is only for the brave! Last year we saw some truly remarkable performances - let’s see if anyone can beat last years record of 9 loops!
This event is open to teams of 4, pairs and solo entrants.
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. The outstanding views stretching as far as Pen Y Fan will make the climb worthwhile. 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 10 hour 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.
The 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.
Refuel Zone
Our Refuel Zone will be stationed at the Start/Finish line. It will be well-stocked so you’ll be properly fuelled throughout the day. We cater for all dietary requirements including vegan. At the Refuel Zone, you can expect to be met with nuts, bananas, sweeties, biscuits, crisps, electrolytes, coke, squash, water and if you’re very lucky, some homemade cake!
There will be space in headquarters for you to leave a drop bag. You can access this drop bag anytime throughout the day. We recommend putting in bits like spare socks, your favourite treats, a spare change of clothes - things that will pick you up when you’re having a hard time. All bags are left at the participants own risk. You will also have easy access to your car if you’d prefer to leave spare kit in there.
Cut Off Times
This is a 10 hour endurance challenge. The horn will sound at 10 hours on the dot (6pm) - if you are still out on the course, the lap you are on will NOT be recorded.

Support Crews
Support Crews are welcome at headquarters but not out on the route. We will try to ensure that there is enough space for everyone, however we have to prioritise our participants. Food in the Refuel Zone is strictly for entrants only. We kindly ask the support crews to vacate the Refuel Zone when their participant is out on the course. You will be allowed to assist them inside the Refuel Zone if they need it, but we may ask you to step outside if it is getting too crowded and other participants cannot easily access it.
There will be parking available, however it is limited so please car share where you can. There will be recycling bins available, so we kindly ask that you use them!

We have a field with toilets within walking distance of HQ for basic camping. No need to book, we’ll share details on the pre-race email.
