Royal Welsh Trail Running Festival 2017

Incorporated into the Royal Welsh Spring Festival, the Royal Welsh Trail Running Festival offers a series of challenging but scenic trail races in the heart of mid-Wales.

Half marathon and 10k and trail courses start and finish in the Royal Welsh Showground in Builth Wells and take in valleys, fields, woodland tracks and stunning forestry. The family-friendly Family and Toddler trail events offer something for all ages.

Race entry fees include a bespoke wooden commemorative medal, technical finishers t-shirt (for half marathon and 10K) and free entry in the Royal Welsh Spring Festival – a celebration of rural life with entertainment, workshops, livestock, trade stand and a street food quarter – the perfect place to unwind after running the trails.

The event incorporates The Welsh Trail Running Championships and Welsh Inter-Regional Trail Running Championships.

The Trail Running Festival is delivered by Run 4 Wales, the mass participation events team behind the Cardiff Half Marathon.

The Wales Air Ambulance are the Lead Charity Partner of the event. We encourage runners to fundraise for them, with donations helping to fund their missions across Wales.
