How far can you swim before the tide turns? The Boomerang swim starts at Bantham (home to the Swoosh), with swimmers heading upriver on the incoming tide. When the tide turns, so do the swimmers, swimming back downriver with the outgoing tide, swooshing into Bantham Beach and the finish line.

The distance swum will depend on how fast you swim, but all swim speeds are welcome. Some swimmers will make it all the way to the turnaround pontoon upstream before the tide turns, others will have a shorter journey.
