Jack Daniels Training Plan customer Stephen Boulet of Palatine, IL set a new PR at the Chicago Marathon this past weekend. Boulet started his plan with a 4:12 marathon PR and a goal time of 4:00. His result: 3:59:04!
After the race Stephen said, “I’m very happy with the strong finish. I ran the last 4 miles at 92% of my max heart rate. I credit the threshold and repetition training with that, an element missing from my training before stumbling across Jack Daniels.”
