Cancer Research launches its Race for Life in Darlington this week.

Women of all ages are being asked to walk, jog or run the 5km route around South Park on Sunday, July 13, to raise money for the charity's fight against cancer.

All entrants in the race, who pay a small administration fee, get a sponsorship form, a training plan and a unique race number.

To be in with a chance to wear the number one, and be entered free into the race, send your name, address and telephone number to: Race for Life competition, PO Box 14, Priestgate, Darlington, County Durham, DL1 1NF, with the answer to this question: Which charity organises the Race for Life?
