Adidas offers seven different marathon training plans, designed by the excellent Greg McMillian. McMillan’s approach is to help runners “feel” the right pace without a heart rate monitor, and the app gives you three levels of intensity—green for easy runs, yellow for fast tempos, and red for when you need to bring the donkey sauce. Overall, the app seems most likely to meet a variety of runners at their individual level, and to teach them how to move their training forward.
