Jump pads arent always the most accurate way to measure you vertical… and not worth for you to buy. You can just put a ruler up on a wall or something like that. You don’t need a lot of expensive things to train with, i know you already purchased those sparq cones, but you are just in HS you don’t need to go crazy with all this specific timing. Especially when the only running you did was 10m. Save your money for college is all I am saying. Where are you training… climate wise? Are you going to have to train inside?
