how long is the pole in the pole vault
Pole vault Because pole stiffness and length are important factors to a vaulter's performance, it is not uncommon for an elite vaulter to carry as many as ten poles to a competition. The effective properties of a pole can be changed by gripping the pole higher or lower in relation to the top of the pole. The left and right handgrips are typically a bit more than shoulder width apart. Poles are manufactured for people of all skill levels and body sizes, with sizes as short as 3.05 m (10 ft 0 in) to as long as 5.30 m (17 ft 5 in), with a wide range of weight ratings. Each manufacturer determines the weight rating for the pole and the location of the maximum handhold band.
