we care about your safety

We want you to feel confident when registering for a BBSC race and those already registered can have peace of mind knowing you have options and will not lose any portion of your race entry. We believe our COVID-19 transfer policy is the best in the industry, going above and beyond for the athletes who choose to race with us.
