A blind man has completed his penultimate run in a worldwide challenge to complete seven marathons in seven days.

Dave Heeley, 50, from West Bromwich, and his guide Malcolm Carr finished the latest marathon in Tunis in four hours and 40 minutes.

Mr Heeley, who calls himself "Blind Dave", and his team will complete the final run in Sunday's London Marathon.

The runner is raising money for the Guide Dogs for the Blind Association.

The team have already finished marathons in Rio de Janeiro, the Falklands, Los Angeles, Sydney and Dubai.

Mr Heeley's family are expected to be at the London race to cheer him on.
