Agility T-Test Score Calculator

Turn your T-test time into an average agility speed.

How it is calculated

The tool does one division: speed = 36.58 ÷ time, where 36.58 m is the total course length of the standard T-drill (40 yards) and time is your completion time in seconds. The answer is an average speed in metres per second, printed with two decimals. Because the distance is a fixed constant, every extra tenth of a second lowers the speed, and the same time always gives the same speed regardless of body size. Times below 5 seconds or above 600 seconds show no result, since a T-test is never run that fast and a longer entry is almost certainly a typing error. The figure averages the whole path including turns and stops, so it is lower than a straight-line sprint speed, and the tool does not rate the time as good or poor.

Worked example

An athlete completes the T-test in 10.5 seconds. The course length is 36.58 m, so the average speed is 36.58 ÷ 10.5 = 3.4838, shown as 3.48 m/s. Multiplying by 3.6 turns that into about 12.5 km/h. If the same athlete cut the time to 10.0 seconds, the speed would rise to 3.66 m/s, so a half-second gain is roughly 0.18 m/s.

Common mistakes

  • Entering the time in minutes or as 10:30. The field is seconds with a decimal point, so 10.5 means ten and a half seconds.
  • Comparing the result to a sprint speed. The 3.48 m/s here includes the lateral shuffle, the backpedal and the turns, so it will always be far below a straight-line 40 m speed.
  • Using a course with different cone spacing. The tool assumes the full 36.58 m path; if your cones are closer, the real distance is shorter and the speed is overstated.
  • Entering a time under 5 seconds, for example 4.5. That is not a realistic T-test time, so the tool shows no result instead of a speed.
  • Mixing timing methods. Hand-timed values are usually faster than electronic gates for the same run, so compare like with like.

About this calculator

The T-test is a standardized agility drill used in sports science: an athlete sprints forward 9.14 m, shuffles laterally 4.57 m to each side, and backpedals to the start, covering a total of 36.58 m that combines forward speed, lateral movement and change of direction into a single completion time. Because the distance is fixed, a faster completion time translates directly into a higher average speed across the drill, giving a single comparable number for multidirectional quickness.

Strength and conditioning coaches use the T-test to assess and track agility in sports that demand rapid changes of direction — soccer, basketball, tennis and American football among them — and it is a common component of pre-season fitness testing batteries and combine-style evaluations alongside sprint and jump tests.

Your T-test time is divided into the drill's fixed 36.58 m route, giving your average speed through the cones.
