Official event pageWhat this race demands
The Hever Castle Swim Series 5 km open-water swim demands exceptional aerobic endurance and prolonged cold-water management in a historic lake and river setting.
Aerobic endurance
Covering a 5 km distance entirely by swimming requires continuous cardiovascular exertion over an extended duration, demanding sustained pacing and stroke efficiency.
Open-water navigation
Racing in lake and river grounds requires consistent sighting and adaptation to variable natural water conditions without the visual aids found in a pool.
Thermal resilience
September open-water conditions in Kent demand preparation for cooler water temperatures over a prolonged exposure period.
Target 30 to 60 grams of carbohydrates per hour using easily digestible gels or sports drinks during training leading up to the event, and utilize pre-race fueling to sustain energy through the continuous swim effort.
