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 Pewsey West Woods and.        
  • Gopher Wood, with its amazing wild garlic.    
  • Two of the highest points in Wiltshire at Knapp Hill and Tan Hill, where the long and short courses diverge

Plus, on the 33-mile route:

  •     The Kennet & Avon Canal into Devizes
  •     Roundway Hill and Morgan's Hill
  •     Cherhill Monument and White Horse

Finally, the routes rejoin to pass through Avebury, with its pre-historic stone circle and views of Silbury Hill, then go via Overton and Fyfield Downs back to Marlborough Leisure Centre for showers and refreshments.
