Josh Kerr started the men's 1500m final at the World Athletics Championships with rich ambitions of retaining his title in Tokyo.
But, a little over four minutes later, Great Britain's Olympic silver medallist hobbled over the line in last place, a calf injury having ruined his hopes and left him adrift of the field.
A field which included childhood pal Jake Wightman, who suffered agonies of his own in being denied a second world title on the line.
His fellow Scot had the significant consolation of a silver medal, but Kerr was left with only frustration and regrets.
The 27-year-old - who won this title in Budapest two years ago - hung back in the opening lap of the race. Standard practice for him, even if he was hemmed in.
