Things went swimmingly when the Maidenhead Lions Club staged its 33rd annual Swimarathon at the Magnet Leisure Centre with 100 teams taking part.

The event lasted all day on Saturday from 7am to 7pm with eight teams starting off hourly - their members swimming in relay while raising money for their favourite charities as they went and splitting the result with the Lions' own chosen good causes.

Prime Minister Theresa May - who is Maidenhead's MP - turned up with her husband Philip to cheer some of the teams on.

During the day nearly 1,000 swimmers of all ages and abilities took part and with £25,000 already expected to have been raised organiser Brenda Butler - the Lions secretary - hopes the final tally will beat last year's sum of £35,000.

Among the causes to benefit were Alexander Devine Children’s Hospice Services, Maidenhead Amateur Swimming Club, Dorney Youth Club, Sportsable, Maidenhead Stroke Club, Maidenhead Sea Cadets, as well as many local school associations, churches and youth groups.

The Lions had also put aside an extra £1,000 to donate to five team's chosen causes - chosen at random from a hat.

The awards evening when the most successful swimmers and fundraisers of the day will be announced is on April 27 at Cox Green Community Centre.

Mrs Butler said: "The atmosphere was amazing and already 58 teams have booked to take part next year."
