Joanne Pitchforth, who teaches at Wakefield Tutorial Preparatory School, Laura Smith and Bruntcliffe High School student Leanne Schofield, who all play underwater hockey, completed their relay swim in just 21 minutes at Batley Sports and Tennis Centre.

Joanne, 39, Laura, 17, and Leanne, 16, play underwater hockey, known as Octopush, for Yorkshire Ladies and Batley. The sport involves each player wearing fins, a snorkel, a mask and a waterpolo hat while they push a puck into the opposing team’s goal with a small stick.

They raised money by inviting people to guess how long it would take them to complete the mile pushing the underwater hockey puck for 64 lengths.

The person who guesses the nearest will either win a cash prize of £25 or a month’s gym membership at the Sports Centre.

Joanne has been playing Octopush for 30 years and won a silver medal at the 2006 World Championships. She is also the current World Bog Snorkelling Champion.

She said: “The idea came from the British Octopush Association, who asked us what we were doing to raise money for Sport Relief, which was all about running, or walking a mile. We thought this would be a great way to do it. We swam it faster than we thought we would and it went really well.

“We just kept taking it in turns and did the mile underwater. We are all pleased with the money we have raised.”

Laura and Leanne have both trained for the Great Britain U19 teams.

Batley Octopush Club is starting a junior session on Sundays from 5.30pm-6.30pm after Easter at the sports centre in Windmill Lane, Howden Clough.

All the money raised will be spent by Comic Relief and will help people in the UK and countries around the world.
