WET TEST · TEAMGOLDUSA SWIMMING PERFORMANCE
Three Minute All-Out Swim Test
The 3MT is a continuous, maximal 180-second front-crawl swim. TEAMGOLDUSA uses a consistent in-water push start, 30-second recording points and the final 30 seconds to estimate critical speed.PRIMARY OUTPUT
What it measures
Total distance, 30-second distance segments and a field estimate of critical speed from the final 30 seconds.IMPORTANT LIMIT
What it does not measure
A medical examination, direct laboratory measurement, race prediction or complete description of an athlete’s fitness.COACH PROTOCOL AT A GLANCE
How to administer the 3MT
- Confirm eligibility, explain stop criteria and complete the standardized warm-up.
- Use the same pool course, in-water push start, timing method and recording setup.
- Start one continuous 180-second maximal front-crawl effort.
- Record cumulative distance at every 30-second signal and total distance at 180 seconds.
- Calculate final-30-second speed and document all test conditions before comparison.

Can 3MT results from yards and meters be compared directly?
No. Keep short-course yards, short-course meters and long-course meters results separate.
