The MTC Thames Challenge

The MTC Thames Challenge is a four-day, multi-stage ultra running event covering a total of 184 miles along the Thames Path from the river source in the Cotswolds to the Thames Barrier in Greenwich. The event is split into four distinct daily races.

  • Day 3: 47 miles Windsor Ultra from Henley-on-Thames to Travelodge Kingston.

Accommodation and food are included for the ends of days one to three, with shared rooms (three per room) at named hotels. Ultra Running Ltd covers the competitors' main evening meal; starters, drinks and desserts are paid by the competitor. Each morning competitors are responsible for moving their own belongings to the start area; one cabin-sized kit bag per competitor is transferred by the support vehicle.

All finishers receive bespoke medals and a technical item for each day completed; the four day medals interlock to show the route. First male and female each day receive trophies. Competitors must be at least 20 years old and carry mandatory kit, including a backpack, head torch with spare batteries, OS Map 150, compass or GPS, whistle, mobile phone, emergency food (two chocolate bars) and a basic first aid kit. A minimum average pace of 4.0 miles per hour is required; those below this threshold will be withdrawn. Visit the organization's website for the most recent information.
