Corn’s not the only one with ears….Cows have them too!  Tell your friends!!  MO’ Rewards

New this year, is the MO’ Rewards program!  We know you have a need for MO’ Cowbell and so do others! When you register to run MO’ Cowbell you’ll receive a link on your registration confirmation email to pass along to your friends and family.  When you get 4 people to register for the Half or Full Marathon (using your personal link) by September 1st, you will receive an official MO’ Cowbell blanket at the ExMO’.  Oooo Ahhh! We know you want one!

Transferring to another MO’ Cowbell Race

If you wish to transfer from one race to another race you may do so by completing the MO’ Transfer Application and mailing it to:

EDC of St. Charles County
Attn:  MO’ Cowbell
5988 Mid Rivers Mall Drive
St. Charles, MO 63304.

There is no transfer fee but you must pay the additional fee if you are entering a race with a higher entry fee. If you transfer to a race with a lower entry fee, no refund for the difference in the amount, will be given.

IMPORTANT: All runners who transfer races will be issued the original race shirt not the transfer race shirt.  For example, if you originally registered for the half marathon, but transferred to the 5K prior to race day, you will be issued a half marathon shirt.  

See you this fall!
