MORSMAN 5 sends triathletes into the Balaton quarry lake in Trzebinia for a winter version of the sport: 200 meters of cold-water swimming, 20 kilometers on the bike, and a 5-kilometer run. The event uses the Balaton bathing area, a local recreation spot with clear quarry water, and it starts in the middle of the day rather than early morning.
The swim can be done in any style, and regular entrants may use wetsuits, neoprene gloves, and neoprene footwear. After the water, athletes can change into cycling gear in a heated room before heading onto an off-road bike leg and a cross-country run. There is also a HARDCORE classification for athletes who skip wetsuits and neoprene accessories, which gives the race its cult, cold-weather edge.
