The basecamp is in the grounds of the historic Penrice Castle, with weekend camping options and the 100km challenge is a figure of 8 route made up of west & east loops which take in the best of the Peninsula, its history, and its varied, unique landscape. With 50km, Marathon, 25km, and 10K challenge options, as well as a bar & entertainment at basecamp – this will be the highlight of the season!

Why run for Cancer Research?
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.
