You can take breaks in this time, and complete in as many runs as you like. You can use the official TCS London Marathon App to log and track your run.

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.
