International Self-Transcendence Marathon Swim
Still Water 8
Lake Zürich is also part of the Still Water Eight and site of the 26.4 kilometer International Self-Transcendence Marathon-Schwimmen. The Still Water Eight is a group of 8 marathon swims in lakes that is a goal of seriously-minded marathon swimmers who are focused on still-water marathon swims. Successful completion of these 8 marathon swims has never been recorded by a single individual. It was first publicly announced by Michelle Macy in October 2011.
Completion of the Still Water Eight can be recorded in three categories:
2. non-wetsuit (i.e., FINA approved swim suits)
3. channel-standard swimwear (i.e., traditional swimming briefs for men and no arm or leg coverage for women)
If the swimmer chooses to swim one of the Still Water Eight swims in a wetsuit, they would fall into the wetsuit category. Likewise if they swim in a FINA-approved swimsuit, they fall in that category. If they swim across all the lakes in channel-standard swimwear, then they fall into the channel-standard category.
Every swim attempt must start and finish on dry land.
