The course is marked by a number of buoys allowing swimmers to complete a loop of approximately 450m. The reservoir swims are Tuesday evenings and Saturday mornings until autumn, with wetsuits obligatory. However there have been a few recent summers, when the water temperature has been warm enough to allow non-wetsuit swims.
