Hi! I already run and have done for a few years. Can comfortabley run 7 miles at around a 9.45/10min mile pace. I feel like I can run more when I get to 7 but do get bored...however I would love to train for a marathon when DS starts school (year and a half a way) and was thinking in the interim it would be good to train for a half...anyone know any good apps or training plans? So going from 10k to half really? Thanks!
