<human>: Give me the gist of the text in a nutshell

This past weekend I ran the Cleveland Marathon in ~3:15. I followed the Hal Higdon Advanced 1 for every workout/run with just a short break early in the program due to injury. Today I am feeling relatively good, not much soreness and am looking to do a 2-3 mile very slow run later. 

I am looking to qualify for Boston later this year at the Erie Marathon, and am looking for advise on how to get started. I was going to follow the same program, with some slight modifications. For workouts, I was going to do only tempo and hill runs (no repeats). Instead of doing pace runs Saturday. I was going to do them in the middle of the long run, and just have an easy run of the same distance Saturday. So my question, how do I get started into training again, what week should I start on, and is there anything I need to worry about.
<bot>: Ran a 3:15 this weekend, want to train for another marathon in early September. Did Hal Higdon Advanced 1, how do I get started running again?
