OTT Marathon & 10 Mile Race

Nestled within the breathtaking Brecon Beacons, the OTT Trail Marathon and 10-mile race promises an unforgettable adventure for trail runners. This challenging course showcases some of Wales' most iconic peaks and vistas.
The marathon route is a loop that begins at Parkwood Caravan Site and takes you through Pen Y Fan via Graig Fan Ddu before ascending to Fan Y Big. The journey continues across Talybont Reservoir, culminating in the final climb up Tor y Foel. After this exhilarating ascent, runners head back towards the finish line.
For those opting for the 10-mile race, you'll follow the marathon route until Checkpoint 1 at approximately seven miles, where you diverge onto forestry tracks leading to Dolygaer and the finish.
Both races offer stunning mountain trails and panoramic views that are a highlight of this event. The aid stations provide essential hydration and energy boosts along with delicious cakes, making the journey all the more enjoyable.
Upon completion, every participant will receive an OTT coaster and buff as a memento of their achievement.
Competitors in both events must bring specific compulsory kit to ensure safety throughout the challenging terrain:
- Marathon runners need items such as reusable cups, fully charged mobile phones, hydration packs with at least 1 liter capacity, emergency rations (400 calories), basic first aid kits, head torches or flashlights, compasses, whistles, waterproof jackets and trousers, warm layers including hats and gloves.
- For the shorter race, essential items include reusable cups, a basic first aid kit, bivvy/foil blankets, 500ml of water, and a waterproof jacket.
The marathon features three checkpoints at key intervals to ensure runners stay on track:
1. Checkpoint 1: At approximately seven miles.
2. Checkpoint 2 (Marathon only): Around the halfway mark at 14.5 miles.
3. Checkpoint 3 (Marathon only): Near the finish line, around 20.5 miles.
The marathon has a strict cut-off time of 6 hours after the start, meaning runners must maintain an average pace faster than 20 minutes per mile to complete all checkpoints within this timeframe and reach the finish by 15:00 at Checkpoint 3.
Race day starts with briefings for both events:
- Marathon briefing begins at 8:50 AM.

- For the 10-mile race, there's a pre-race briefing at 9:50 AM followed by the start at 10:00 AM.
