David Weir wins the London Marathon men's wheelchair race for a seventh time

Britain's David Weir has won the men's wheelchair race at the London Marathon.

The 37-year-old clinched victory on Sunday in one hour 31 minutes and six seconds after a sprint finish to beat defending champion Marcel Hug by just a second.

Weir, taking part for an 18th consecutive year, won the Paris Marathon earlier this month and sealed victory in London for the first time since 2012.

Rafael Botello Jimenez was third after a dramatic finish on The Mall as Weir passed Tanni Grey-Thompson's six victories.

Six-time Paralympic champion Weir had hinted he was ready to postpone retirement to continue to focus on road racing, after he walked away from Team GB following last year's disappointing Paralympics.

In the women's wheelchair race Switzerland's Manuela Schar took the title for the first time.
