30 kids raced that day - 150 showed up the following week. And so, organised BMX racing was born. In almost any kind of racing, there is a certain amount of required safety equipment. You may want to borrow one from TTG BMX club until you're certain you are going to continue racing. A pair of cotton, wool, or leather racing gloves.
Leather wears better than skin.
A pair of jeans or track pants will do until you are ready to get a pair of racing pants. Long sleeve top or racing top. Any long sleeve top will do the job until you decide to opt for additional padding, then get a factory racing top. You will look good and feel more a part of what is happening. Kickstand, chain guard, reflectors and similar street items.
