I am following the FIRST training plan found here: http://www.firstrunningcalculator.com/first-half-marathon-calculator/

You can plug in a recent race time and it generates a pace-based training plan. I needed one that was 3 days a week and this works out good for me. This is based on the book "Run Less, Run Faster" which I highly recommend.

I'm following hal's intermediate for my 3 and 4th half. Keep in mind I'm much slower than you, I'm trying to get from 2:11 to 1:57. I find his long runs to be a little modest though, so I'm upping them. My cutback weeks will be 9 mile long runs and the rest of the time it will be between 10-13, running 13 3 times in the 12 weeks. So you could consider the intermediate or advanced with slight modifications.

I used Higdon's intermediate plan for my first half marathon, the advanced for my second, and then I felt comfortable writing my own plans for marathon and ultra distances. I think Higdon's plans are solid, but everyone's different. If you don't feel like you're getting the right gains, try something new!

I like Hal and his programs. They are simple, like me....

I've looked at FIRST, Runners World, Hidgon, Daniels, and, most recently, McMillan.

As a new runner, the RW plans were easy to follow but there's not much variety. FIRST sort of fell by the wayside for me - I like running 4 days a week and riding the bike just doesn't do it for me.

IIRC, Higdon was time based and, at the time, I was more tuned in to miles vs time.

Daniels - I use parts of his book to calculate training load (as well as FirstBeat Athlete and iThlete which have been very good tools for me) but I never took the time to get my head around his training plan.

I've got a Half in August and I was using an RW plan until about a week after I got back from a McMillan running camp. While at the camp, I bought Greg's book ("You - only faster" - "YOF") and I was going to continue with the RW plan to get me ready for August. Funny thing happened - when I read Greg's book, things clicked for me so I switched over and I love it.

YOF is available in hard copy or digitally (Kindle) and it's got background on how the plans are structured. At the start of the book are a variety of plans for different races and, for each distance, there are different plans according to the number of days you want to train. YOF then describes the different types of runs (endurance, stamina, speed, and sprint) and shows how to vary your plan if you're a "speedster" or an "endurance monster".

As a new runner (at the 1500 mile mark), I don't really know that I'm neither a speedster or an endurance monster so I'm running the stock Half plan, running 4-5 times per week. I'm doing a variety of runs and I'm enjoying it thoroughly, far more so than a plan from RW.

The author of the site has filled his Wiki chock full of information and tips and I found that link, like the rest of his site, to be very helpful.

If you want a 1:30. You've gotta run a advanced plan with good speedwork options. I've run a HH advanced 2 and a cool runnings intermediate before, i really liked them both. I got a 1:36 after running HH advanced marathon. A lot of runners here swear by the LSR method of running where they do lots of mileage all the time, you could maybe look into running a marathon programme to get a bit of extra basework in.
