Thame Swimming Club youngsters Hannah Hawken and Georgia Cahill excelled at the recent SE Youth Championships at K2 Crawley.
Both girls smashed their previous personal bests in the 50m freestyle with regional times for an Olympic sized pool.
Cahill, 18, also swum the 100m backstroke followed by the 50m backstroke in a time which placed her 11th in the 17 years and over category.
The following day both girls were at it again with further achievements.
Both flew out of the blocks as they aced their 100m freestyles to gain another set of long course regional times.
A successful weekend for Hawken, 16, also meant she managed to climb 10 places in her ranking out of South East England’s swimmers.
Meanwhile, the club decided to brave the cold water at Bray Lake for its first ever open water session on Saturday.
