About the Race to the King

Write your own piece of history in the heart of the South Downs as you chase the King from ancient coast to sweeping ridges.

Whether you are a first time Ultra runner or a hardened professional there is something to test everyone in this ultra-accessible figure of 8 ultramarathon challenge. The hardest part might just be waving goodbye to your supporters at the festival camp for your second loop.

50km Coastal takes you along the coastal path of Chichester Harbour AONB, through the picturesque ancient village of Bosham. If Castles are your thing, 50km Castle route winds along the River Arun, past Arundel Castle and up along the South Downs Way before heading back to the finish line.
