Join us in 2020!

At Race Day Events, our #1 priority is keeping our athletes, volunteers and staff safe. With the new circumstances we have all been thrown into, we are doing our best to adapt and continue to produce safe and enjoyable events. This is a labor of love for us and a passion of both yours and ours. We look forward to the day we are back to normal. Until then, we will continue to work with local health departments, municipalities, and the state to responsibly put forth plans to best adapt to the changing guidelines. We will keep you informed and updated as we traverse this new “course” together. As always we are here to support your goals, dreams, and ambitions. We will get through this together. Can’t wait to see you at the START LINE!
