Thames Trail Ultra
In partnership with the Thames Path and Ridgeway National Trails - sensibly priced ultras for crazy runnersThames Trail Ultra
A 47-MILE POINT-TO-POINT ALONG ENGLAND’S LONGEST RIVER
This demanding run along the Thames is one of the most popular events in the British ultra running calendar.
Previously known as the Thames Trot, the event takes in 47-miles from Iffley in Oxfordshire to Henley-on-Thames.
Our runners will enjoy the company of England’s largest river as it makes its way past ever-changing scenery, beautiful houses and traditional rowing clubs. Expect everything from tarmac paths to muddy trails on this interesting and challenging course.
The run follows both the Thames Path and Ridgeway National Trails, so entrants should be careful not to forget the words ‘National Trail’ rather than simply reading Thames Path.
Starting around three miles south of Oxford, the race heads from Hawkwell House Hotel down to Iffley Lock and across the river. It then follows the towpath through the picturesque towns and villages of the region to Henley-on-Thames.
There will be a new race finish from 2024 at the YMCA Y Centre, in Lawson Road, Henley-on-Thames. This will mean runners will be able to access showers, hot food and drinks, and changing facilities at the end of the race – more details can be found here.
We are proud to say that this race is an Ultra-Trail du Mont Blanc index race.
