🎒 Personal Gear

We will not have a gear check. We are not aware of any past problems with items left in vehicles. The parking lot is a relatively safe area and the risk can be further reduced if valuables are not left in plain sight. We will not be responsible for any lost or stolen items so please plan accordingly.

The temperature on race day is usually mild. The average low is 46° F, the average high is 64° F, with an average mean temperature of 52° F.

🔄 Changing Races

Race switches from the full marathon to the half marathon and vice versa must be completed before the end of Saturday packet pickup at the latest. There will be no refund for transferring down to a shorter race and a fee for the price difference will be charged for transferring up. There will be a $10 service fee for all transfers. If you are unable to make it to Saturday packet pickup, email us before Friday so that we can make a new bib number and assign a new chip.

You can pick up race packets from 1 pm to 6 pm on Saturday, September 13th, at the Hampton Inn (1860 S. Burlington Blvd) in Burlington. This is the best day to pick up your packet to avoid long lines during packet pick-up on race morning.

📅 Day of Race Packet Pickup

Race packets can be picked up on the morning of the race at Burlington-Edison High School from 6:45 am until 8:00 am. It is preferable to pick up your packet the day prior to the race in order to avoid long lines the morning of the race.
