Colfax 5K
Come run City Park in the Colfax 5K! Go for a PR in this chip-timed race – separate stroller-friendly start wave for families and walkers. And, you can run with your dog in the dog wave presented by Evolution Veterinary Specialists! Afterparty with live music. A great chance to be a part of Marathon weekend – at a much shorter distance.
NOTE! – We have two 5K’s. The main 5K is at 9:00am, and there is an additional 5K on Saturday for just the Girls On The Run starting at 10:30 if you’d like to stay and watch. The Girls on the Run 5K has their own shirt and items, and dogs are not allowed.
