Official event pageWhat this race demands
Prom'Swim demands sustained open water endurance to complete a 10 km swimming distance in the Baie des Anges at Nice.
Open Water Endurance
Covering a 10 km distance requires high aerobic capacity and the ability to maintain efficient freestyle stroke mechanics over an extended duration without wall-pushes or resting.
Sighting and Pacing
Navigating an open water course in the Mediterranean requires continuous sighting skills and disciplined pacing to avoid early burnout during a long swim effort.
A 10 km open water swim will likely exceed 2.5 hours for most athletes, requiring a strategic intake of 60 to 90 grams of carbohydrates per hour via liquid nutrition or gels sourced from a support craft or feed station.
