This Saturday James and a colleague will be swimming 421 lengths of the main pool. They will be alternating continually until they hit their target. That works out at just over 10.5km!
Why 421 lengths?
As the state of poolside is in need of repair and we are repairing the tiles we have chosen 421 lengths as it is the number of tiles that run around the top row of the waterline in the main pool. If we raise enough we wish to renovate more of the poolside.
