Simply the BEST!

I do a lot of marathons and mud runs this app is on point and the best in instructional advice. I workout daily and its really motivates you to push harder without noticing what your doing to yourself...(if you follow what they say). Just from changing my diet a little, and wearing a weighted vest every two days. I went from running a 8mile pace to 7-6:5 pace. Itll be nice if they would make a gps with a drill sergeant. coaching you.
