Q) Is there an age requirement for each event?

A) The MCMO’s review of current sports medicine peer-reviewed literature addressing the participation of children in distance running events reveals consistent concern for overuse injuries, stress fractures and psychologic burnout.  The consensus conclusion of medical experts is that children should only participate in endurance running events under close supervision from health professionals, and with a full medical evaluation before initiation of training, throughout training, as well as 6 to 12 months post-race.  Since the MCMO is not staffed to verify such a detailed and prolonged medical process, and is also fully committed to ensuring our events are staged with health and safety as top priorities, we are not prepared to allow children under the following minimum ages to participate in MCMO events:

The Turkey Trot Mile runs in November and is open to all ages.
5 to 12 years of age for the MCM Kids Run.
Not less than 10 years of age for distances greater than a mile up to and including 10K.
Not less than 14 years of age for distances greater than 10K up to and including the marathon.
Not less than 18 years of age for the 50K distance.
