noun - Two hundred one hundreds (200 x 100s) is a pool swimming distance freestyle interval set that is a tradition among the hardest core open water swimmers, channel swimmers, and marathon swimmers. Two hundred swims of 100 yards or 100 meters each, or a total of 20,000m or 20,000 yards, is conducted in a pool, either on one consistent interval or performed at different intervals. The set is usually done during the year-end training period.
