CHALLENGE BENEFITS
We all have non-running friends who think that runners are a little off. They can’t understand why you do it and might event even call you names behind your back. Runners, on the other hand, KNOW they are a little crazy and are proud to boast about it!
The Baltimore Running Festival has come up with a way for our wildest runners to get their kicks and poke a little fun at the fact that most people think they are nuts!
Runners who complete both the half marathon on and the 5K on Saturday will receive:
- A special Baltimoron race bib valid for both events
- Earn an exclusive Baltimoron medal in addition to the half marathon and 5K medals.
- A $5 savings if you regster for both races at one time using the BUNDLE option.
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 Baltimoron (and let them know to run the other way… very quickly!).
HOW TO REGISTER (& SAVE $5)
Select the BALTIMORON-A-THON category in the registration process and we will make sure you receive your special 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!
