How the approach differs
High jumpers run a curved J-approach, usually 8 to 13 strides, that lets them rotate into the bar and kick the lead leg up at takeoff. Vaulters sprint a straight runway of 18 to 22 strides while carrying a pole that can weigh several pounds, then plant it in a fixed box just before takeoff. The vault approach demands far more raw sprint speed; elite vaulters carry close to their open sprint speed into the plant, something almost no high jumper needs to worry about.
