Switch Your Distance

After 7/31, runners wishing to change their race distance have the following options:

Please note, your personalized bib, with your name, streak, phrase, chip, and distance, has been ordered and is on its way.

If you’d like to drop down in distance: 

No problem! You can drop down on race day, the timing mats will detect what you ran, and you will be an official finisher of that distance. There is no need to notify us in advance.

Be sure to follow the route for your chosen distance (volunteers may see your bib and try to redirect you) and tell the finish line volunteers what you ran so you receive the appropriate finisher medal.

When you pick up your bib, you can try to swap it for a new one at packet pickup on Friday or Saturday before the race. There may be extras available.

If you’d like to increase your distance:

You can try to upgrade your distance when you pick up your bib at the expo on Friday or Saturday. Upgrades will be based on bib availability. A fee equal to the race price difference will be due if you decide to upgrade (cash or check only).

Starting and ending in historic downtown St Charles, IL, the course winds through picturesque Geneva, Batavia, North Aurora, and Aurora to a spectacular finish across the Fox River that can be seen from over a mile away. The course offers fantastic viewing spots for families and supporters, as well as frequent and well positioned aid stations that are staffed by the most supportive volunteer teams of any race you’ve run.
