Bury St Edmunds Leisure Centre receptionist Jenny Magnus will brave a swimathon in 6C water on February 23 in aid of St Nicholas Hospice Care.
The 25-year-old will take the icy plunge for the hospice’s Big Chilli Dip at Moreton Hall Health Club and must swim at least 10 lengths in 6C water.
At the end , entrants receive a bowl of chilli to warm up.
Jenny, of Ixworth, who is using the leisure centre’s pool to train, said: “I have never done anything like this before, so I don’t really know what to expect, except that it will be very cold.
“I decided to take part to raise money for St Nicholas Hospice as I feel they do a brilliant job, and I have a soft spot for the work they do from my own personal experiences.
“I always love a new challenge, I took part in a half marathon last year in Cambridgeshire, and this year I am looking to take part in a bike ride for The British Heart Foundation London to Brighton in June.”
She has worked at the Leisure Centre since December and will be cheered on at the Big Chilli Dip event by her partner Alex and family and friends.
Jenny added: “I would consider myself quite a confident swimmer but I have never taken part in anything like this before.”
Clare Maller, acting manager at the centre, said: “Abbeycroft is proud that a member of our reception team Jenny Magnus is taking the challenge and plunging herself into the Big Chill Event in aid of the St Nicholas Hospice Care. All the staff at Abbeycroft wishing Jenny well for the event.”
