Basically to get started, you will need a swim suit, cap, goggles, sneakers, a bike, and don't forget the helmet. In a race you have to wear your helmet. In fact you can't unclip it until you are off the bike no exceptions, safety first please. I got my helmet at Target for $15- 20. It is important to try them on and see how they fit and
adjust the straps. There are all shapes and sizes of head so take your time. I have a hard to fit head just ask my family they refer to me as "pumpkin head".
