Swimming 30km for turning 30

Jubilee Park Woodhall Spa's Park Manager is turning 30 (don't worry everyone thinks hes older)- To celebrate hes planning to swim 30km in one day on the 6th August. Thats 900 lengths of Jubilee Park's heated outdoor pool.  The money raised will go towards building a gym and updating the pool buildings at the park which in turn should help us further secure the future of the park.
