Coach Neil Boston Marathon Qualifier Training Program Master Runner Coaching Online Virtual Plan

Neil offers his passion for running, knowledge from successfully training and racing since 2014, and many years of coaching and developing others professionally.  Neil ran his first marathon in 2015 at age 53 which was a life-changing experience.  After this, he studied popular advanced training methods and created his own plan that took him to his first Boston Marathon in 2017 (his BQ streak continues).  


In late 2018 Neil hired Cal not only as a coach but to give him a crash course in the basics of endurance running, running physiology, and advance methods of training (from 5k to marathon distances).  


Neil is committed to sharing his knowledge with others looking for a similar life-changing experience through running.
