Marlborough Downs Challenge

The Marlborough Downs Challenge runs two trail races around Marlborough across the North Wessex Downs. The routes are mostly off-road on tracks and footpaths and include rolling countryside and notable local features.

Distances:

  • 33 mile trail (approx 32.69 miles) with around 3000 ft of elevation.
  • 20 mile trail (approx 18.94 miles) with around 1500 ft of elevation.

All competitors register at Marlborough Leisure Centre to collect race numbers and must attend the pre-race briefing. The start area is on Marlborough College parade ground and the finish is at Marlborough Leisure Centre, where toilets, changing rooms, showers and refreshments are available. A drop bag room is provided at the Leisure Centre but it is not supervised.

The races are self-navigation. Competitors must carry printed maps or independently downloaded GPX files, or carry an independent electronic navigation device with sufficient battery. GPX files are updated regularly and are provided in pre-race information issued to entrants.

Marshals will be positioned on course and aid stations will offer supplementary water and snacks. A mandatory kit list applies, including a water container, cup, charged mobile phone, food, survival bag or foil blanket, maps or independent electronic device with spare battery, and sunblock or warm clothing as conditions require.

Prizes are awarded for first to third male and female in each distance and for age groups V40, V50, V60 and V70. All finishers receive a souvenir mug. Both races are licensed by the TRA and held under UK Athletics Rules. Age limits apply: entrants must be 18 or over for the 20 mile race and 20 or over for the 33 mile race.
