Hannah, aged 27, who was exercising with her sister Sophie, thought nothing of her own welfare when she dived in and pulled Maria to safety.

Maria and her partner, Tom Grainger never had a chance to find out who the mystery rescuer was but the Herald has now put both parties in touch with each other.

“My clothes were soaking and it was a cold morning so I couldn’t hang around although I would have liked to and had a cup of tea with Maria and Tom. Maybe next time….. on dry land though!” Hannah said.

Hannah, who has a degree in sport, is centre manager of Aspire an organisation which helps people with spinal injuries.

She’s now in training for the Ride-London 100 challenge and her fundraising is www.justgiving.com/HannahBladon100
