How to Bridge the Gap

Here's the gap. I ran a 3:39 on my last marathon. And I need to break a 3:10. I've finally realized that I need to scratch my entire workout plan and create a new one, which is good because I never had a workout plan.

Up until a few weeks ago, I was just running twice a week up the trail at a comfortable pace for 10 or 15 miles. Problem is that I wasn't getting any faster. After making some changes over the last few weeks, here is what my schedule is evolving toward:

1. Not Running Slow: Yep, simple as that. How do you expect to run a 7:15 pace for 26.2 miles if all your 10-15 mile runs are at an 8-minute pace? My goal is to get my distance runs at a 7-minute pace. This means that a 7-minute pace should feel comfortable, not like I'm about to keel over. My last 10-miler was at a 7:35, so I'm on my way.
   
2. Intervals: Once per week. I only do these if I can round up a couple friends for 40-minutes of pain. Because intervals suck! We do this workout on a high school track, and start with a mile warm-up. During the warmup, we jog the turns and sprint the straightaways. Then we get into the sprints: two 800s, two 400s, and two 200s. We have a two-minute break in between each interval. I've done this workout four times now.
3. Hills: Once per week. These are like speed work in disguise. I run 3.5 miles to a hill I discovered, run up it, walk down it, repeat a number of times, then run home. I've done this workout three times now. Next weekend I'll be bamboozling a friend into doing this workout with me.
4. Tempo Runs: I just read about these in Runner's World, and haven't done one yet. They say this run should be a 15-minute warmup, followed by 20-minutes at the "tempo pace", then finished with a 15-minute cooldown. To figure out my goal for a tempo pace, I checked with the McMillan running calculator. It says that for a 3:10 marathon I should shoot for a tempo pace between 6:36 and 6:53. Holy smokes!! Well, that ain't gonna happen for now, but I'll report back on my progress.

I've also been getting in an extra workout or two throughout the week. So now I'm running 3 or 4 times per week. Hopefully this will slowly bridge the gap for me so I can accomplish my goals.
