The Challenge

The ultimate team endurance event! Walk, jog or run 100km non-stop across the South Downs Way in under 30 hours as a team of four.

The event weekend

Friday 27 September

Arrive from 4pm at Queen Elizabeth Country Park and register your team. Once registered, you’re free to enjoy the atmosphere, fill up on pasta at the army field kitchen, and set up camp for the night.

Saturday 28 September

After a hot breakfast from the field kitchen, the teams set off in waves, starting at 6am. Down the trail you’ll meet your support crew, and a hot meal will be available at Checkpoint 7 to see you through.

Sunday 29 September

Most teams reach the finish line at Brighton Racecourse early on Sunday morning. You’ll arrive to a hero’s welcome from our volunteers and Gurkha pipers, a medal, and a delicious Nepalese Gurkha curry.

Support Crew

Your support crew will drive a vehicle between checkpoints to meet you, delivering food and additional kit. You must have a support crew of at least one, but we strongly recommend two. It will be an epic adventure and a big achievement for them too, as they support you physically and emotionally across the 100km route.
