Race Information

The Marlborough Downs Challenge offers two events
33 mile* Trail Race 
20 mile* Trail Race 
* Note that distances are approximate only.

The MDC is a beautiful yet challenging event, mostly off-road along tracks and footpaths. There is plenty of climbing - over 3000 feet for the 33 mile race.  The routes take in some of the finest Wiltshire countryside including:
  • The Wansdyke Path, Tan Hill Way, White Horse Trail, and Mid Wilts Way with superb views across the Vale of PewseyWest Woods and.        
  • West Woods and Gopher Wood, with its amazing wild garlic.    
  • Two of the highest points in Wiltshire at Knapp Hill and at Tan Hill, where the long and short courses diverge
    and, on the 33 mile route,
  • The Kennet & Avon Canal into Devizes
  • Roundway Hill and Morgan's Hill
  • Cherhill Monument and White Horse
After the two routes rejoin to pass through Avebury, with its pre-historic stone circle and views of Silbury Hill, runners then go via Overton and Fyfield Downs back to Marlborough Leisure Centre for showers and refreshments.
White Horse Pottery hand throwns mugs for all finishers!
