Hi! I'm on week 8 of C25K and plan to train all the way to a full marathon and hopefully be able to run my first one in November. I am a bit confused, however, whether I go from the C25k app to a 10k and begin there on the first week and so on until the full marathon app or should I just start with the full marathon app from the beginning? Thanks for whatever info you can provide.
