A series of incredible, life-changing challenges
The Threshold Trail Series is a collection of breath taking ultra marathons. Each route is designed with precision to show off the very best of the great British countryside. Fully supported, these events are perfect for those taking their first-step into the world of ultras, to seasoned athletes seeking a new challenge. Whether you walk, jog or run, do it in one day, or stay overnight at our legendary basecamps – we have tailored packages to suit everyone.
In 2013 we launched Dixons Carphone Race to the Stones and it quickly became a firm favourite in the events calendar. With a brimming medal wall of its own, including the UK’s best endurance event at The Running Awards 2016, we’re proud that this event is growing from strength to strength.
More Is In You
At Threshold Sports, we believe in pushing ourselves to always achieve more, inspired by our mantra ‘more is in you’, we couldn’t just stop at one event. In 2016 we were delighted to welcome the inaugural Race to the King, and this year we are introducing our very first HEINEKEN Race to the Tower.
HEINEKEN Race to the Tower
The newest addition to the Threshold Trail Series, this is a double marathon along the Cotswold Way finishing at the foot of the magnificent Broadway Tower.
Race to the King
Race to the King is a double marathon along the stunning South Downs Way, with a finish fit for a King or Queen at Winchester Cathedral, the burial place of the first Kings of England.
Dixons Carphone Race to the Stones
Our original ultra marathon, Dixons Carphone Race to the Stones is 100km along Britain’s oldest path. Voted the UK’s best endurance event at The Running Awards 2016.
