Richard Kilty defended his 60m gold title from two years previous, with Asha Philip also taking the title over the same distance, while Andrew Pozzi won the 60m hurdles. Robbie Grabarz, Lorraine Ugen and Shelayna Oskan-Clake celebrated a triumvirate of silver medals, while the 4x400m relay team and 3000m runner Eilish McColgan took bronze.
And for British Athletics performance director Black, a strong medal haul in Belgrade has left him purring at the possibilities at what could come when his athletes take to home comforts this summer.
"I'm really thrilled for the team and the performances we've seen this weekend," Black said.
"It's been great to see Laura Muir come away with the double gold she was aiming for, but also wonderful to see Andy Pozzi, Richard Kilty and Asha Philip on top of the podium. It was great to see Eilish McColgan battle for that bronze; there were world-class performances from Lorraine Ugen, Robbie Grabarz and Shelayna Oskan-Clarke; and it was great to see different relay athletes coming through to challenge for gold - their time will surely come!
"This year is very much about London 2017, and this will have given great insights to athletes and coaches on where they are performance-wise."
