Yep. I used it to train for the color run last spring. Loved it, ran a 5k easily. Took some time off when life got in the way and re-used it but only halfheartedly and ended up getting injured at my zombie run in October, almost broke my ankle. I am reusing it now to train and get my 5k base back, and after that I will move on to a 10k
ETA: check out Run The Edge too, they have various programs and they get really good reviews
