After years of juggling three disciplines, discover what happens when you master just one.
Focusing on one sport lets you master it in a way that juggling three cannot. UltraSwim 33.3 gives that focus a clear goal: 33.3km of open water across four days. Many swimmers find deeper progress and satisfaction when all their training points at a single discipline.
UltraSwim 33.3 is an Epic Adventure Swim Race™ covering 33.3km, the historic English Channel distance, split across five to seven point to point open water swims (we hate laps) over four days in warmer water locations (a half Channel 17km option exists). So far held in Croatia, Switzerland, Greece, Spain, Montenegro and the Caribbean, based at luxury spa hotels, with world class safety cover, premium support, a complete preparation programme and a diverse community that ranges from 14 to 74 years old, usually more women than men. From competitive Masters swimmers, triathletes and swimrunners to leisure and wild swimmers simply aiming to complete the distance. From a required pace of just 2km/h, any determined swimmer can do it. Come in a group or alone, everyone leaves with new friends for life. Award winning, all inclusive packages start from €1,575 CHECK (€750 for our 2 day Compact format)

Swimmers reflect on the freedom of training for one sport instead of three.
Faster technical progress, deeper endurance and a clearer goal. Training is simpler to plan and recovery is easier to manage than across three disciplines.
You will specialise, which is the point. Your aerobic base carries over, and swimming becomes your strength rather than one of three.
Open water swimming offers huge variety in locations, conditions and distances, so focus does not mean monotony.
