Nut Job Challenge

Over the years, we have learned that some of our participants are certifiably nuts! Many of you can’t get enough running and are always looking for the next challenge. Well, now we have just the thing for you! We are proud to announce the Annual Frederick Nut Job Challenge.  Runners who complete both the half marathon on Sunday and The Twilight 5K on Saturday will receive a special Nut Job race bib valid for both events AND earn an exclusive Nut Job medal in addition to the half marathon and 5K medals. Medals will be distributed following the completion of the half marathon. Your special bib will help our volunteers and everyone else identify you as a Nut Job (and let them know to run the other way… very quickly!)


A prize will be awarded for the 1st place overall Male & Female in the Frederick Nut Job Challenge – awards are based on the combined finishing chip time in the Half & 5K.


Select this category in the registration process and we will make sure you receive your special Nut Job race bib at pick-up. By registering using this category you will SAVE $5 OFF your total combined registration fee. If you have already registered for one of the race distances but did not register for the Nut Job, simply register for the other race and then fill out the form below to let us know you are a Nut Job!

The deadline to link your races together into the Nut Job Challenge is April 19 at 11:59pm.

Please Note:  If you register for each race separately and link them together into the challenge, you waive your right to the discount.

The deadline to merge your Nut Job has passed. Please email [email protected] if you would like to be added to the waitlist. Thank you.
