Event details
The MTC Thames Challenge is a four-day multiday ultra running event on the Thames Path in England, held 6–9 August 2026. The full route covers 184 miles from the Thames source in the Cotswolds to the Thames Barrier in Greenwich. The event is organised by Ultra Running Ltd and based at Kemble Station, Cotswolds GL7 6AW. Entry options include solo and relay categories; the solo entry fee is listed as £595 and a relay member fee as £425. A deferral option is available for a fee.
Race format and logistics
The challenge is split into four stages, each run as a separate ultra. Competitors must be self-sufficient and carry mandatory kit: backpack, head torch with spare batteries, Ordnance Survey Map 150 or organiser maps, compass or GPS device, whistle, mobile phone, emergency food (two chocolate bars) and a basic first aid kit. Accommodation and the main evening meal are provided at the end of Days 1 to 3; rooms are generally shared three per room, with private rooms available at extra cost. One cabin-sized kit bag per competitor is transferred by the support vehicle each day. The organisers operate checkpoint recording and enforce a minimum average speed of 4.0 miles per hour; falling below this limit will result in removal from the race.
