Stillwater 8 Swimmers

Categories

Completion of the Still Water 8 can be recorded in three categories:

1. wetsuit
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 8 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.
