CALLUM HAWKINS collapsed with heat exhaustion when leading the Commonwealth Games marathon with one mile to go.

The 25-year-old from Elderslie had a lead of more than two minutes over Australia's Michael Shelley at the 40km checkpoint in the 26.2 mile race but collapsed and could be seen writhing on the ground after struggling amid hot and humid conditions which reached 32 degrees celsius.

The Scottish runner was shaky on his feet, zig-zagging across the road and running into a spectator, with native Gold Coaster took over to retain his title. There was at least a happy ending for Scotland with Robbie Simpson taking the opportunity to claim bronze.

Hawkins was taken to hospital for medical review following his collapse and is being supported by Team Scotland medical staff but there are no major concerns at this stage.
