A record-holding runner is being forced to relinquish his title after race organisers discovered the route was almost 500ft too short.

Callum Hawkins, 24, beat the Scottish half-marathon record previously held by Haile Gebrselassie with a time of one hour and 22 seconds last October.

But the course for last year's Great Scottish Run has now been found to be almost 500ft (150 metres) short, invalidating records and personal best times set at the event.

It means Hawkins' record, which beat the previous time set by Ethiopian double Olympic gold medallist Gebrselassie in 2013, will be wiped away.
