This fantastically runnable Ultra Marathon will test your limits as it takes you through the heart of the Brecon Beacons on beautiful, but technical trails. 

The ultra starts at George town boys and girls club in Merthyr Tydfil and works its way onto the Taff Trail. After a few miles, you will split away to follow the trails alongside the River Taff heading north towards the Beacons Reservoir.

Once at the far end of the reservoir, the route crosses the A470 and climbs to the summit of Pen y Fan (the highest peak in South Wales at 886 meters). Once at the top, a descent of Jacobs ladder will lead you to the Roman Road taking you to Torpantau.

From here you will take the forestry track alongside Dolygaer and Pontsticill Reservoir, providing fantastic views over the valley.

As you descent from the forest tracks, you return to the trails of the Taff Fechan Nature Reserve as you follow the river back to the Taf Trail , which you will follow until you are back at the club. 

 This is a great route for those looking to take the step up to a trail Ultra marathon whilst also catering to experienced ultra runners. 

There are 5 checkpoints for the race, 4 will have water and food available:

– Checkpoint 1 at Cwm Cadlen Road crossing at 6 miles.
– Checkpoint 2 at Pont yr Daf car park at 13 miles
– Check-in/Check-out-only checkpoint at the Pen Y Fan summit.
– Checkpoint 3 at Torpantau Train Station at 19.5 miles.
– Checkpoint 4 at Ffynnondwyn (Taff Trail) at 26 miles.

The cutoff for this event is 14:00 at checkpoint 3. This is 6 hours after the start of the race, so a pace of approx 19/mile or quicker is required of entrants
