After 14 years we are making some changes to the format of the classic South Downs Marathon Day. The routes of marathon and half marathon themselves remain unchanged but we are taking out the marathon relay and introducing a trail 10km in Queen Elizabeth Country Park.

South Downs Trail Marathon & Half Marathon routes

Starting at Slindon College at 9.00am the full marathon runners follow a route up onto the South Downs through woodland reaching the South Downs Way at 5.5 miles, then running west back to the finish at Queen Elizabeth Country Park. The free buses to take marathon runners to the start will depart from QE Park with the full marathon runners between 7 and 7.15am.

Drink stations: 5.5, 7.5, 13, 17, 20, 23 Miles. Gels at 13, 20 Miles.

New: We have introduced a cut off time of 7hrs on the route with intermediate cut-offs of 3hrs 15mins at 13 miles and 5hrs at 20 miles. Runners outside these times will be returned to the finish by minibus. This has been introduced as we can’t keep the marshals and medical coverage out of the course for the increasingly extended periods of the last runners in the last two years.

    I really enjoyed this. It was really well organised, brilliantly marshalled and signposted. It was a bit hilly but that was part of the fun! Im definitely doing it again this year. After some hill training!!
