    The hike will set off in waves 20 minutes apart, from 7.00am for the full marathon and 8.00am for the half marathon. 

    You will book your start wave when you register. These are given on a first-come, first-served basis and we advise hikers with a slow pace to book the earliest start wave available to give plenty of time to complete the route.

    For the full marathon, we estimate that the fastest walkers will finish in around 7.5 hours while the slowest walkers could take around 12.5 hours.

    For the half marathon, we estimate that the fastest walkers will finish in around 4 hours while the slowest walkers could take around 6 hours. 

    If your plans change, don’t worry, you can amend your start wave using our Manage My Booking page.

    Parking for the full marathon will be at Brighton Racecourse, BN2 9XZ. Parking for the half marathon will be at Bramley Farm Bootfairs in Polegate, BN26 6QN.

    You can book parking when you register.

  • When does registration close?

    Registration for the full and half marathon closes at midnight on the Friday 30 May, one week before the hike, or earlier if it sells out.
