Sussex Downs Trail Run - 22km

The Sussex Downs Trail Run on 6 December 2025 takes in the picturesque views of the South Downs National Park in Mid-Sussex.

Starting from Plumpton Racecourse, the 22km route includes picturesque and unspoilt views, fast and long-ranging trails and a challenging climb - something for everyone. By running and raising funds, you'll make a life-changing difference for children and families affected by neuroblastoma and other childhood cancers.
