First half marathon in March how can I prepare?

Seems like ur in shape already. Just working out + add weight lifting to ur workout. I suggest running in uphill roads as much as possible to get better and do lifting for endurance. TRY MAKING UR WORKOUT HARDER THAN THE ACTUAL RACE.

If u worry too much about being embarrassed u won't do good. A bit nervousness is completely fine but don't get overwhelmed.

Here 's a trick I learned. Right before the race starts, accept u r nervous and u r afraid of embarrassment for about 10 seconds(no more) . Then, take a deep breath in through the mouth and blow out these feelings. Do this for 3-5 times. After this, just forget ur fears. Concentrate on the race don't get discouraged and u will do fine.

If you can already run more than 10 miles, you could go finish a half marathon right now. From your details, it sounds like this is the case - although you do need a better measurement of your long runs, you are certainly not running 13 miles in an hour, you'd be an Olympic-caliber 5k runner if that was the case.

You can find a variety of structured half marathon training programs online, I recommend the ones available at www.runnersworld.com, but a Google search will turn up a lot of them. For a longer race like a half marathon, make sure you're getting at least 4 days of running per week, 5 or 6 if you can handle it. The shorter runs during the week (easy runs, speed work, etc.) are just as important as that weekly long run when it comes to preparing for these kinds of races. Treat your weekly long run as race-day practice - try to drink (and eat, if you plan to) during the run at the same intervals that you will during the race.

Again, I suspect you already have the conditioning needed to finish a half marathon, you just need a bit of structure to your training and some time to learn more about longer races to be able to turn in a pretty decent time when March comes around.

Do what I'm doing. Lift weights and only run a mile a day. Helps me.
