The test requires 500 yards continuous swimming: 25 yards crawl, 25 yards free style back stroke, 25 yards breast stroke, 25 yards side stroke and 400 yards additional swimming any stroke plus 3 minutes of treading water. (This translates into 20 lengths (10 round trips) of the pool — 1 crawl, 1 backstroke, 1 breaststroke, 1 side stroke, and 16 lengths any style — plus 3 minutes treading water.) THERE IS NO TIME LIMIT. Most people complete the test in under 30 minutes, but you can take as long as you need.
