Race to the King

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.

You will be treated like royalty on your journey with fully-stocked pitstops, laden with food and drinks, and tireless support from our crew and medics. This is a challenge for all, inclusive of all ages, experience, and fitness levels. Whether you’re a seasoned runner, patient plodder or weekend walker – take on 100km in one go, or 50km in one day via the coast or castle.
