Dive into open waters at Merchant Taylor Lake for Rennie Grove Hospice Care (2)

Choose your distance Open Water Swim Challenge​!

Raise funds by setting yourself a challenging distance in this Hertfordshire lake, or simply get sponsored to dive in to the chilly water.

Take on our "get in and splash challenge" and ask your friends and family to sponsor you to support your brave efforts and raise £30 ​which would fund an hour of physiotherapy to help patients live independently for as long as possible.

Or you could challenge yourself to swim as many loops as you can in the session (100m, 500m, or 750m) and aim to raise £150 to fund 5 hours of specialist care from a hospice at home nurse helping patients to stay at home with their families and make every moment matter.

Following fantastic feedback from our 2021 launch event, we are offering a new and exciting swim series for 2022. You can choose to book either the Open Water Swim Challenge in May or the Open Water Swim Festival in July or even take on the "double your distance Challenge" and take part in both.

Our family fun Open Water Swim Festival is on 16 July 2022 from 10am - 3pm.

You can find out more about it here . Select "Series Ticket" on the booking form to obtain your discounted Series Swim ticket to attend both May and July events.

If you raise £150 in sponsorship, we will send you a  ​Rennie Grove OWS Towel and if you can raise over £250, we will send you a ​Rennie Grove OWS hoodie.​

There will be toilet facilities and changing facilities at the lake however, participants are recommended to arrive ready to swim.

There is ample parking at the site.
