I've modified the running schedule to where it will fit me best. I've decided to run everyday and repeat some of the days until I feel comfortable and strong enough to move to a new week. I was wondering would it be better if I repeat the days while just improving my speed on the jogging sections or should I move up another week where the time has increased but am still running at the same pace or even less? Either way I am improving but I don't know which one is more safe or if anyone has advice on this.
