Abstract
A hurdle assist includes a flexible tubular lower section comprising a first length and a first slit along the first length, a flexible tubular upper section comprising a second length and a second slit along the second length, and a flexible rod which is slidably removably coupled with the flexible upper section. Attaching the hurdle assist to a hurdle mimics a flexible hurdle for the runner to practice without fear of injury.

DETAILED DESCRIPTION OF THE PRESENTLY PREFERRED EMBODIMENTS
(9) FIG. 1A depicts a perspective view 100 of a hurdler 102 running over a hurdle 104 comprising a barrier section 106. The hurdler 102 is tasked to run on a track that includes a number of hurdles, such as the hurdle 104, and run over the hurdles by raising his right foot to clear the barrier section 106 and then to raise his left foot behind his torso to clear the barrier section 106. According to prior art, the hurdler 102 uses the hurdle 104 during training. The hurdle 104 is made from rigid material and the hurdler 102 is fearful of making contact with the hurdle 104 causing the hurdler 102 to fall down or otherwise cause injuries.
(10) FIG. 1B shows a perspective view of a hurdler 110 running over a hurdle 112 having a barrier section 114 that uses the hurdle assist which includes a coupler having a flexible tubular lower section 116 and a flexible tubular upper section 118, and a flexible rod 120. The flexible tubular lower section 116 is removably coupled with a distal end of the barrier section 114. The flexible tubular lower section 116 includes a slit (see for instance, FIGS. 2A and 2B) which can be easily connected to the distal end of the barrier section 114 without having to use fasteners such as bolts, screws, or adhesives. The flexible upper section 118 also includes a slit (see for instance, FIGS. 2A and 2B) which is used to easily insert the flexible rod 120 into the flexible tubular upper section 118. Utilizing the hurdle assist 116, 118, 120, the hurdler 110 can practice by running over the flexible rod 120, thereby, avoiding injuries that would otherwise result from running over and making contact with the barrier section 114 of the hurdle 112.
