We worked with Scimitar to create Cancer Research UK sportswear that’s comfortable, looks great and supports our vital work. 20% of the price of these products will be paid to Cancer Research UK.
Every step we make towards beating cancer relies on every mile, every pound and every person. Play your part and join our dedicated team to support our fundraisers on the day. Our volunteer opportunities for the marathon are now closed, however we have plenty of other events that need your support.
