Bustinskin Events have built up an impressive list of events in the past 20 years. Based in Weymouth and Portland, they make the most of Bowleaze Cove, Weymouth Bay and the Isle of Portland. The Aquathlon series and open water swims are based at Bowleaze Cove, to the left hand side of the bay. The Jurassic Coast is used for the bike and run sections of triathlons of varying distances.
