Karen Woo, who grew up in Stevenage and attended The Barclay School, was shot dead in August 2010 while on a trip to provide medical help to Afghans in critical need.

The 36-year-old was killed along with nine others.

To support a charity set up in Karen's name, her brother David ran the Leamington Spa Half Marathon in July, Kenilworth Half Marathon in September and Rugby Half Marathon on Sunday.

He achieved a collective time of five hours and 26 minutes - smashing his six-hour target.

The Karen Woo Foundation is a grant-giving charity supporting healthcare and education in Afghanistan.

David, who raised £930, said: "I wanted to honour Karen's memory and help continue her aid work."
