I used the link, the last 5k I ran was 31'46. The link says I should run the half at an 11'13... which to me seems really slow, I could go out tomorrow and run that and not be tired.

How long ago was the 5k? As you're still new to running, you will see a great deal of improvement in a short time. (Won't last forever)
This is one of the reasons I like training by heart rate-you run at the same rate and your pace will speed up on it's own as your fitness improves.

A half marathon pace will feel easy through the first part of the run. Feeling good at 6 doesn't mean you'll feel that way at 13.1.

My last 5k (race) was in the summer... I didn't really start running again until about 2 months ago. I probably couldn't do a half tomorrow, but at the pacing it says I feel like I'm doing a brisk walk/easy jog (i'm 6'4 mostly legs) so I'll just keep going at what feels right and use the guide as a suggestion

If your pace feels good, stick with it.

Run a 10K late Feb/early March-you'll get a better idea of your fitness and can get a good estimate of your half mara. time.

2 mile run tonight in 19:15

Lookin' good!

Parents went to bed and I wasn't tired so I went for a run. 8.1 miles in 1:27:34... started out strong but at mile 6.5 I slowed down drastically. Still okay with the time and distance though since it's been my longest for both so far.

New Year.... New Goals

Hooray New Year!

I dropped about 45 pounds and went from 34%BF to 26%BF in a year

Now looking to drop another 30 and get to around 15%BF

That's wonderful . I see good things for you in 2012
