The Achilles tendon is the strongest tendon in the human body. On average, the Achilles tendon of an adult is 150 mm in length and 20 mm in cross section. Surprisingly, it is quite elastic; it can store and release energy like a spring. But it's a very stiff spring, with a spring constant of approximately 2.5 x 10° N/m The force on the Achilles tendon while running can be 7 times the runner's weight.
