When is the 2021 Naperville Half Marathon & 5K?
The 2021 Naperville Half Marathon & 5K will take place on Sunday, October 17. Both races begin and end on Eagle St., just north of Aurora Ave. The half marathon begins at 7 a.m. The 5K begins at 7:15 a.m.

I’d like to switch from the Half Marathon to the 5K, is that possible?
YES! To switch from the Half Marathon to the 5K, run the 5K on race day and make sure you enter the 5K finish chute on the west side of Eagle to receive your 5K medal. NOTE: running the 5K instead of the Half will affect your Legacy and Multi-Race Challenge medal status.

I’d like to switch from the 5K to the Half Marathon, is that possible? Yes, you can modify your race through your account, subject to availability. There is an upgrade fee to change from the 5K to the half marathon. The paid 5K race fee will be credited toward your new race.

Can a friend pick up my packet?
YES! Just bring a copy of their ID with name and date of birth. A picture of the ID on a phone is acceptable.

Is this a good race for a first time half marathoner?
ABSOLUTELY! This is a scenic course with spectator spots along the course so your fan club can cheer you on.

How does the group discount work?
Register 3 or more runners at time of registration and each runner receives a $5 discount! Here’s how it works: Your group will need to designate a one person to register your entire group. When you log into the registration site choose how many people you are registering (3 or more is required for the discount). Fill in the required information for each registrant and pay with a credit card. The group discount will be automatically applied at checkout. Note: the group discount is valid ONLY for the Half Marathon.

Are runners who are under 18 allowed to register?
Runners age 14 and over on race day can register for the half marathon, but should be sure it will not interfere with their high school team eligibility before registering. Runners age 8 and over on race day can register for the 5K.

What will the weather be like on race day?
We won’t predict the weather so far ahead of time but historically the day brings pleasantly cool temperatures with a high of 60 degrees and a low of 41 degrees. And cool temperatures mean faster race finishes.

How long is the course open?
The course road blocks will be taken down and aid stations will begin closing at a 13:45 per mile pace for the half marathon and a 20 minute per mile pace for the 5K, which is a 3 hour total half marathon or a 1 hour 5K time.

We ask that all runners and walkers that register for this event are prepared to complete their event during the time restriction listed above.

Those who finish outside of the time limit will not be recorded as official finishers and may not receive full on-course support from Aid Stations and traffic personnel.

Please indicate your anticipated finish time during registration.

I am registered. How do I change my email address or any other personal info?
That’s simple. Confirm your registration and choose the option to update your data. You will not be able to update your name or email. They are you identity in the registration system. You will have to re-register, and email us at so we can void and refund your incorrect registration.

What fuel will be available on the course?
Gatorade Endurance Formula is on course at this year’s Healthy Driven Naperville Half Marathon, fueling you throughout the entire race.

As part of a five-electrolyte blend, which includes sodium, potassium, calcium, magnesium and chloride, Endurance Formula is a specialized sport drink designed to help maintain hydration during prolonged training and racing when fluid and electrolyte losses can be significant.

It contains nearly 2x the sodium and more than 3x the potassium of Gatorade Thirst Quencher to help maintain hydration and proper fluid balance and help replace the critical electrolytes lost in sweat during these occasions. Find Endurance Formula online at or at a Sport-Specialty retailer near you.

Can my friend pace me for part of the race?
NO. The only people allowed on the course during the race are registered runners. We provide an official team of pacers for you to run with. A participant who has received pacing by persons not officially participating in the event may be disqualified.

Having a friend join you for part of the race either on foot or bicycle is also frowned upon by other runners and may earn you some ill will.

Is there an early start?
NO. The half marathon and 5K will start at 7:00 a.m.

Will I get a medal?
Each FINISHER of the Healthy Driven Naperville Half Marathon & 5K will receive their medal when they cross the finish line.

What do you use for timing?
Our race will be timed using disposable timing tags, which are attached to your shoe.

Is there a wheelchair division?

Unfortunately our 2021 course will not be able to accommodate a wheelchair division.

Are pets permitted?
Service animals are permitted to accompany their owners.  Out of respect to other runners, some of who may be nervous around animals, we request that runners with service animals start at the back of the start corral.  There is no need to buy an entry for your animal.  The race is for people only.  It would be unfair for people to have to compete with animal participants for awards, and our volunteers and medical teams are not equipped to handle animal behavior or emergencies.

Do you allow jogging strollers?
For insurance and logistical restrictions: no dogs (with the exception of a service dog), no strollers, no bicycles, no roller blades, no in-line skates, and no wheeled vehicles are allowed in the half marathon. Strollers are permitted in the 5K. Strollers will be in a unique corral with an anticipated start time of 7:25 a.m.

What is the Flag Warning System?
There will be a simple flag color system along the course to help warn participants of weather related or course related problems. Flags will be located at each aid station along the course.

  • Green Flag: Running on schedule: Course and weather acceptable.
  • Yellow Flag: Weather advisory: runners take appropriate precautions.
  • Red Flag: Extreme weather: runners advised to slow or walk.
  • Black Flag: Race is closed. Make your way back to the finish line, but no official finish times will be given.

Are there awards?
The Half Marathon features Top 3 overall awards, and also Age Group awards, which are 3 deep for Male and Female runners. All awards must be picked up on race day. They will not be mailed.

The age of a participant on the day of the race determines his or her Age Group / Masters classification.

Age Groups:
24 and under,
and 75 and over.

How fast will you sell out?
It is difficult to determine how fast the race will sell out each year. Our advice is the REGISTER EARLY to secure your spot at the start line.

I am injured and/or cannot run the event (family commitment, work obligation, etc.). Can I donate my entry or transfer my entry to someone else?
No. All registrations are nontransferable and non-refundable as stated in the waiver you sign when you register. Please note that according to our rules, transferring or selling registrations or bibs is not allowed and both runners will be disqualified and banned from future events.
