This is the heartwarming moment a marathon runner proposes to his girlfriend at the end of the race - wearing a t-shirt reading 'Will you marry me?'.

Romantic Jonny Black, 43, popped the question to partner Kathryn Keir, 41, after finishing the Edinburgh Marathon.

The keen runner had a personalised top made which read: “Kathryn, will you marry me?” on the front and “Popping the question if and when I reach the finish” on the back.

Shocked Kathryn, a civil servant, was at the finish line cheering on boyfriend Jonny, who ran the race in four hours and 27 minutes.
