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.

Why run for Cancer Research UK?
Bridie has taken on the Great North Run six times as part of Team Cancer Research UK. She fundraises in memory of her Dad, who died of bowel cancer.
My first runs were really hard, but I trained and persevered, and I got better. On the day of my first Great North Run I wore my Cancer Research UK vest with pride, I was so happy to be taking part. The atmosphere was amazing and crossing the finish line I was ecstatic! I was so proud of myself and how far I’d come. Every step is worth it. For every person we lose to cancer, it spurs me on even more to continue fundraising so that we can find a cure.
