Switch Your Distance

After 8/31, runners wishing to change their race distance have the following options:

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, 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). 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.

Race Deferral

Participants can defer to the 2026 Naperville Half Marathon Races. The deadline for deferral is 11:59 p.m. CST on 8/31. 

  • As an alternative to deferral, participants can switch to the virtual race and keep their Legacy streak.

  • Limited to the first 50 deferrals.

  • Charity registrations are not eligible for deferral.
