starting week 4 and looking ahead

I'm doing Day 2/Week 4 today and excited about it. Never thought I could run this long without stopping beofre!

I finished the program about 6 weeks ago and ran my first 5K. Since then I have been running every other day 30-40 min. not worrying about time/distance, just keeping a steady pace. On the other days I either walk or ride my bike. I just found that going back to the intervals did not help my endurance. Now I run (really jog) without feeling like I am going to die! Good luck!

I'm starting week 4 tomorrow. I'm excited about what this means for my body, but pretty darn intimidated about all that running! On the one hand, I'm excited to have a (slightly) shorter run. On the other, I've been relying pretty hard on those walking intervals. I know I'm going to have to take my speed down (and therefore my distance) and that's kind of discouraging, but I'm hoping that I'll have built it up again by hypothetical race day.

As I get into straight running I'm starting to think about what comes next. Should I just start the program over and focus on speed/distance? should I just keep up straight running? I'm thinking about starting the program over but instead of 1 walking/3 running going to the same overall time (or nearly) with 1 walking/5 running, then moving on to 1 walk/6 run. Any thoughts? Anybody?
