Sarah began swimming with an Hertfordshire competitive swimming club at the age of 7 and remembers well the excitement of participating in the (fairly newly formed) Peanuts league!!!

During her time with the club she also competed in biathlons and triathlons and latterly became interested in modern pentathlon which combined her love of swimming with her other passion, horses!

She has always loved swimming and following a career in the city as a private equity lawyer she returned to teaching and coaching with a particular focus on young swimmers just starting out on their competitive swimming journey.  All three of her daughters have swum with CoStA and she tries to instil in the young swimmers she coaches the clubs philosophy of swimming fast but having fun along the way.
