Winter on the Downs

Winter on the Downs is a set of single-loop trail ultras that start and finish at Plumpton Racecourse, Lewes, in the South Downs. Routes run on grass trails, farm tracks and woodland or chalk paths and are described as largely runnable with rolling hills and some longer, steeper climbs. The terrain is almost entirely trail with very little road and generally good drainage, though some sections can be wet and muddy.

Typical winter weather ranges from crisp sunny days to strong winds, rain, sleet, thick fog, freezing temperatures and snow. The event takes place on the eastern side of the South Downs and is offered as part of the South Downs Triple Crown challenge. Minimum age for entrants is 20 and a race qualifier is required; qualification standards vary by distance.

Distances and key race facts:

  • 50 km
  • 55 miles - 7,000 ft ascent, 8 aid stations
  • 100 miles - about 12,700 ft ascent, 12 aid stations

Included for participants are a fully signed and waymarked route, a bespoke finisher item (medal or buckle), winner trophies, downloadable photos, live GPS tracking and chip timing, event insurance, and first aid and medical cover. The races are UTMB Index events offering ITRA points. Visit the organization's website for the most recent information.
