The Carmel Swimming Club, who train at the Dolphin Centre before College, every Wednesday attempted to swim 12,900m (516 lengths) to match the number of the days the Dolphin Centre has been open.
Thirty swimmers took part and actually managed to swim 1640 lengths (41,000m), which is about 25 miles.
They were each sponsored by friends and family and between them are raised £1000, which they presented to the Mayor of Darlington and St. Theresa’s Hospice.
A special mention to Nina Taylor who managed to collect nearly £200.
The Dolphin Centre very kindly provided Hot Chocolate and Muffins to all of the pupils.
Many congratulations to everyone who took part.
