Radcliffe (pictured) will take part in the race at London's Battersea Park on May 4, the first of 162 races throughout the UK, culminating on July 31. The events are based around a sponsored 5km walk or run and as many as 425,000 women are expected to take part.
'Tesco Race for Life is a fantastic opportunity to raise money for Cancer Research UK,' said Radcliffe. 'If more women can start exercising more regularly and eating more healthily, hopefully we will get one step nearer to reducing cancer cases.'
Radcliffe won yesterday's London Marathon for the third time, coming in at 2 hours, 15 minutes and 25 seconds. Since becoming national sponsor for Race For Life in 2001, Tesco and the event have together raised£52.5 million.
