Both went on to compete for Team GB in the same event at the Olympics in Rio de Janeiro last month.
Now, Scotland’s future in the multi-stroke event also appears to be in very good hands.
Last weekend, Scottish swimmers enjoyed medal success at the UK School Games, where they competed at the state-of-the-art Olympic-size swimming pool at Ponds Forge in Sheffield.
Ryan Retson (Graeme High School), representing Scotland South & East, and Nikki Miller (Mearns Castle High School), representing Scotland North & West, claimed gold in the boys’ and girls’ 400m individual medley.
One of the most impressive swims at the Games was by Firrhill High School’s Keanna Macinnes. The Edinburgh youngster set a new school record of 1:01.99 in winning the under-16 butterfly.
Keanna is accustomed to setting new marks – she holds the 100m and 200m butterfly record in the 13-14 years age group from the Brodies Scottish Schools’ Championships.
