Official event pageWhat this race demands
The Dock2Dock 15 km swim demands sustained endurance and continuous open-water pacing within London's Royal Docks.
Aerobic endurance
Covering a 15 km distance requires a high level of cardiovascular efficiency and the ability to maintain a steady freestyle stroke for several hours.
Sighting and navigation
Open-water swimming in a dock environment requires consistent sighting to maintain a straight course over an extended distance.
Thermal regulation
A September swim in London requires preparation for potential cool water temperatures over a prolonged duration.
Given the extended duration of a 15 km swim, athletes should consume 60 to 90 grams of carbohydrates per hour using liquid or gel nutrition suited for open-water conditions.
