Training Programs

Congratulations! You’ve signed up to race (or are strongly considering it).  Now it’s time to train.  To help get you started, we have listed a few resources below that you might find useful.  These resources (including their content, training programs, and methods, etc.) were prepared by third-parties and are not specific to, tested by, or otherwise connected with the Colfax Marathon.  Training for a race is highly personal, and so it is your responsibility to figure out what training program works for you and will help you get to the start line healthy and ready to have fun and accomplish your goals.

Your pace and run walk run® ratio of each workout is customized to your ability, plus the Jeff Galloway Run Coach App gives you complete control as you move through your workout.
