Event Info



Saturday, June 11th, 2022

It's time to get muddy, and we've got all the info you'll need to get ready for the big day!

NOTE - REVISED RUNNING TIMES:  We've made changes that affect the majority of runners to make a better running experience for all participants. There will be (4) waves (start times) for 2022: 10:00 and 10:15 am KIDZ Family Waves and 11:00 and 11:15 am Adult Waves.  Those who originally singed up in the 10:30 KIDZ Family Wave will run at 10:15 am.

All Adult Waves have been converted to 11:00 or 11:15 am start times. Your confirmation email will not reflect this change. We will fill up the start chute with 250 runners on a first come basis that will take off at 11:00 am. All remaining participants will leave the start chute at 11:15 am, our final wave of the day. Mud Factor is most fun when waves are full. Making this change will ensure that no one is running in a smaller than anticipated wave. Thank you for your understanding.


Mud Factor TOPEKA takes place on HMP side property with gate entrance on SW Gary Ormsby Drive at SE Adams Street. DO NOT use Heartland Motorsports Park main entrances. DIRECTIONS HERE. Gates open at 9:00 am. You'll want to show up ONE HOUR prior to your wave time to allow enough time for parking, registration, etc. Event held rain or shine.

PRINT a copy of your order confirmation email (or save it on your phone) for faster check-in. Bring your Photo I.D. along with your signed waiver to the registration tent.  A Parent / Guardian will pick up MF Kidz bib(s). There are multiple lines for regular bib pickup. For registration changes (transfers, wave time changes) and day of event registration, use the marked POST REG/ Customer Service Line.
