What are my options if I cannot participate once I have registered?

All entry fees are non-refundable. Sale and/or transfer of race entry/bib numbers is strictly prohibited. Race deferrals will be considered until 2 weeks prior to Race Day. There is a $20 processing fee (this covers the cost of shirt and medal that were purchased for you). PLEASE NOTE: Deferrals are only valid for the following year’s race. For example, a deferral from a 2020 race will only be good for use on a 2021 race. NO deferrals will be accepted on Race Weekend.

Defer Registration

How do I switch races? (Ex: from the Half Marathon to the Marathon)

Runners who wish to transfer from one race to another may do so through their race profile. There is no refund for a runner who downgrades from a more expensive registration choice/race to a less expensive one. If a runner would like to upgrade to a more expensive race they will be automatically be charged the difference in entry fee.

Transfer Race

How does the hoodie fit? Can I exchange my hoodie if it doesn’t fit at the ExMO’?

We know it is all about the swag and we want you to proudly wear it! All participants will receive a fleece-lined hoodie. They are gender neutral.

If your hoodie does not fit, please bring it Info Tent on race morning. We will grant hoodie exchanges while supplies last.

Runner Packet Pick-up

Where do I go to pick up my race packet?

There is no race day packet pick-up.

All runners who did not purchase the mail packet option MUST visit the ExMO’ to pick up their bib, hoodie, cowbell, sticker, and any pre-purchased merchandise.  The ExMO’ includes exhibitor and vendor booths from companies and organizations that promote fitness and healthy living.

MO’ Cowbell Health & Fitness ExMO’ Hours & Location

Friday, October 4: 12 – 7 p.m.
Saturday, October 5: 9 a.m. – 3 p.m.

Location: St. Charles Community College – 4601 Mid Rivers Mall Dr, Cottleville, MO 63376

Can I pick up my packet the morning of the race?

No. Sorry, we do not have race day packet pick-up.

What if I cannot pick up my packet at the ExMO’?

You have two options:

  • Participants unable to pick up their own race packet may have someone else pick up their packet for them.  No special documentation is required.
  • For $40 extra, we will mail out runner’s packets before the week of the race. This option is only valid to the first 200 runners who sign-up for it when they register. Not valid on registrations after September 8th. We encourage you to sign up early because when this option is gone, it’s gone!

General Information

Is the course walker friendly?

We are often asked if walkers are welcome and we happily say ‘yes!’ We just ask that everyone maintain a 16-minute mile pace. If you are unable to maintain that pace, we will ask you to move to the sidewalk and finish the race obeying the traffic laws as we re-open the roads.

Is MO’ Cowbell Marathon a Boston Marathon qualifying course?

You bet! This USATF Certified Course can be used as a qualifier for other races such as Boston, New York and London marathons.

Is there a course time limit?

Yes. The half marathon course route re-opens to traffic at a rolling schedule according to a 16 minute-per-mile pace beginning 20 minutes after the official race start. The full marathon time limit restrictions are 6.5 hours. The finish line will officially close at 2 p.m. The time limit rules will be strictly enforced, if you need clarification before registering, please contact us at

Any participant who does not complete the event in which they are registered will be listed as “Did Not Finish,” or “DNF.” This list will be separate from the official results.

Where are the restrooms along the course?

There will be port-a-potties at the start/finish line as well as at every water station approximately every 2 1/2 miles along the course.

Is there a minimum age requirement?

You must be at least 14 years old to participate in the Marathon, Half Marathon and Half Marathon Relay. Anyone under 14-years-old, with documented running experience (ie: has a finish time for a comparable race), may be allowed to race in MO’ Cowbell on a case-by-case bases. Permission can be  granted by race officials prior to registering. Email

Are bikes, rollerblades, or strollers allowed on the course? What about headphones? Can my pet run with me?

Rollerblades/inline skates, bikes, motorized vehicles, and pets on the course are prohibited.  Strollers/baby joggers are permitted on a case-by-case basis with permission of the Race Director.

What is your weather policy?


The event organizers reserve the right to alter or cancel the event due to inclement weather if conditions are deemed to be unsafe.  Please note refunds will not be issued in the event of a weather-related cancellation.


Announcements will be made over the PA system at the event. As we are able, we will communicate delays and schedule updates on Facebook and Instagram. Please follow @MOCowbell for real-time updates.

Weather Procedures:
If lightning is detected within 20 miles of the venue we’ll enter into a “Heads Up” mode, watching the weather pattern to see if the lightning is moving towards the venue.

If lightning is detected within 10 miles or less we will begin safety procedures and encourage participants and spectators to seek shelter. The course and Athletes’ Village area (including the tent area) must be completely cleared by the time lightning is within 6 miles.
The start will be delayed until the storm has passed or 30 minutes after the last lightning strike is detected at a distance greater than or equal to 10 miles. We’ll do our best to communicate a “restart time” giving athletes adequate time to get warmed up and to the starting line.

Post-Race Information

How do I know if I won a Cowbell Trophy? Where can I pick it up?

Visit the MO’ Results/ Big River Race Management Tent  after the race to see if you won a Cowbell Trophy. All winners can pick up their awards at the MO’ Results/ Big River Race Management Tent located behind the Info Tent in Runners’ Village across from the Jaycee Stage in Frontier Park.

How do I see my race photos?

Finishers will be able to view and purchase their photos from their individual results page. The link to the results page can be found on MO’ Cowbell’s home page the day after the race. We try our best to get photos of all of our runners crossing the finish line but sometimes we miss someone – they also take quite a while to upload. If for some reason we didn’t get photos of you, contact and we will do our best to locate some.

What if my time didn’t register or my results are inaccurate?

Please contact with your name, email, bib number and issue and we will do our best to look into your claim and correct it.

What if I lost/found a personal item at the ExMO’ or in Runners’ Village?

Lost items should be turned into the MO’ Cowbell booth at the ExMO’ and the MO’ Info Tent on race day. This is also the location to recover missing items. After the race please contact us at to request the lost item. If we have it, it will be available for pick up from 7:30 a.m. to 4:30 p.m. M-F at our offices 5988 Mid Rivers Mall Drive, St. Charles, MO 63304. MO’ Cowbell is not responsible for lost or stolen items.
