FAQ

In-Person Race FAQs

Q: What will on-course support be like?
A: We will provide several water stations on course, but likely not as many as in a typical race.

For more information, please check out our Safety Measures page.

Q: What social distancing requirements can I expect at the race?
A: Unless you are from the same common household, we ask that all runners stay socially distanced while in the event areas, including but not limited to packet pick up, start line, on course, finish line and the post-race festivities.

Q: What can I expect at the finish line?
A: The finish line will be broken down into chutes, when you cross the finish we ask you to put your mask back on. While navigating the finish line chute, you will need to remain socially distanced and you will receive a finisher medal and pre-bagged snacks, water and beer (21 and over.) We ask that you continue moving through the finish area - no standing or waiting inside the finish line area will be allowed.
