Swimming sensation Amelia Maughan, swimming for England South, claimed a new Games record in the Girls 50m Freestyle with a time of 26.38.
A faulty start meant that the swimmers had to take to the blocks for a second time but the disruption did nothing to deter the experienced Maughan who swam to a clear victory over the rest of the field.
Hayley Williams, swimming for England Central, claimed silver in 27.48 with bronze going to Scotland North Wests Riona Plowman in a time of 27.85.
Im over the moon with that, said an excited Maughan. I havent really been training and I was on holiday the week before so to come here and set a new PB and get the Games record was amazing.
Speaking of the start she added: Its the first time Ive ever had a start like that: I didnt know what was happening! Im really pleased I was able to stay focussed. I could feel the lactate building up in my legs but I was still hyped up and ready for the race.
