Summary Tendons of 12 equine forelimbs were loaded until failure using a drawbench. Preceding the tensile test, the cross sectional area was measured at the narrowest site of the tendon. Small beads were sutured to the tendons, as markers for length change measurement from photographs. During loading, photographs were taken at about 3 Hz and the load was recorded. The maximal strain was calculated by means of linear regression of length‐time data and extrapolation to the instant of failure according to the force‐time curve. Total failure of the superficial and deep digital flexor tendons, the distal check ligament and the suspensory ligament occurred at a strain (± sd) of respectively 10.9 (± 1.4), 9.5 (± 1.5), 12.4 (± 1.0) and 11.6 (± 1.4) % and at a stress of respectively 116 (± 21), 133 (± 14), 86 (± 11) and 70 (± 12)MPa.
