Weir 'mentally drained' after losing at the IPC Grand Prix

Great Britain wheelchair racer David Weir said he felt "mentally drained" after he finished fifth at the IPC Grand Prix on the final day of the Anniversary Games on Sunday.

Weir, who won four gold medals at London 2012, lost to Swiss Marcel Hug in the men's 1,500m T54.

After the race Weir told BBC Sport despite not feeling at his best he will be back to full fitness next month for the World Championships in Doha.
