Team GB picked up a surprise silver with Mary John overtaking Netherlands' star Femke Bol when she fell yards from the line while battling for gold as the United States won.
For Ireland, the performace continued a remarkable run for the mixed relay team who also competed in the final at the World Championships in Oregon last year, as well as the Olympic final in Tokyo.

It was a time inside Olympic qualification though.
