Siobhan, who trains at the Bath National Centre for Swimming at the University of Bath, hit the ground running on the international swimming scene when she represented Great Britain at the London 2012 Summer Olympic Games aged just 16.
She followed that feat with an outstanding performance as an 18-year old at the Glasgow 2014 Commonwealth Games where she returned home with six medals, including gold in the 200m individual medley. She did it in style, setting both British and Commonwealth Games records.
In August 2015, Siobhan reaffirmed her ability on the world stage when winning bronze in the 200m individual medley and record-breaking gold in the 4x100m medley relay competitions at the World Championships in Kazan.
With the momentum from those outstanding performances, Siobhan continued on her road to Rio in 2016 and secured an Olympic place when she won the 200m individual medley event at the British Swimming Championships in Glasgow.
Her brilliance didn’t end there, though, and in July she ended her Rio preparations in style by breaking the British 100m breaststroke record at the Scottish National Open Swimming Championships.
Siobhan’s outstanding international reputation was boosted once more in Brazil where she won silver in the women’s 200m individual medley.
She produced a sensational performance in the final to take another second off her own British record and touch the wall in 2:06.88.
That was just three-tenths of a second behind Hungary’s Katinka Hosszu, who had to set a new Olympic record.
“When I looked around and saw the time I was over the moon,” she said. “It’s the best feeling in the world.”
