Out With the Old - In With the New is a two-day 5K run/walk in Rochester, Michigan, scheduled for New Year’s Eve and New Year’s Day. Runners begin on the Clinton River Trail behind the Rochester Avon Recreation Authority building, with check-in at RARA each morning. Participants can register for Out With the Old, In With the New, or both days as an OLD/NEW double. Daily registration is limited to 270 participants, maintaining a smaller scale than larger holiday events.
The course combines rail trail sections with dirt paths through Bloomer Park, featuring a mostly flat profile. Both races follow the same route, but the direction reverses on the second day, offering double runners a varied experience without changing locations. Each day provides a unique finisher medal, and the two medals interlock upon completion of both events. The Out With the Old race includes a T-shirt exchange where participants can swap a clean old race shirt for another, while the In With the New race concludes with waffles and mimosas. Awards are presented to overall male and female finishers and broad age categories, with Neighbor Hood House serving as the charity partner.
