The Thames Trail Ultra is a 47 miles point-to-point ultra-marathon on 6 February 2027 that follows the Thames Path and sections of the Ridgeway National Trails. The route starts at Hawkwell House Hotel in Iffley, south of Oxford, and finishes at the YMCA Y Centre in Henley-on-Thames.
The course includes 40.4 miles of cross-country trails and riverside paths, and 6.6 miles of roads. Total elevation is approximately +947 ft (+289 m) gain and -1053 ft (-321 m) loss. Surface types range from tarmac paths to muddy trails; trail shoes are recommended for much of the route, though road shoes may be suitable for later dry sections.

Baggage transfer is provided from start to finish with a maximum bag size of 56 x 45 x 25 cm. The event uses a GPS tracker that uploads position frequently to a live map. The published cut-off time is 11.5 hours with progressive cut-offs from checkpoint 3. Entry fee is £80 and includes the tracker. The event is restricted to participants aged 18 years and over.
