What is injury insurance? How is it different than health insurance?
Injury insurance protects you against unexpected medical cost due to physical injuries sustained during the race. It can be supplemental to your health insurance, off setting the out-of-pocket cost when you're injured. You can go to any licensed Physician for treatment.

What do I do if I get injured?
Go get help! Spot's injury protection will reimburse you up to $20,000 for any treatment to your race-related injury as long as it is provided by a licensed physician. Be sure to use your health insurance during your visit if you have it to help offset any other costs related to treatment.

* includes a $1.00 administration fee
