London Marathon 2015: David Weir motivated by defeat

Six-time Paralympic champion David Weir says he is motivated for Sunday's London Marathon by getting "beaten badly" by a leading rival in last year's Lisbon half-marathon.

Marcel Hug of Switzerland - the man who beat him in Portugal last year - also narrowly won last year's London event, denying Weir a record seventh wheelchair title in the capital.
