...here are some things I would recommend you do between now and then.
1. Google Hal Hidgon, and follow his "novice" training plan. I did his when I ran my first half, and it was about the
easiest plan I've ever seen. Of course, you'll be walking the miles instead of running them, but the important thing is
to follow his plan to the letter. If you do that, you WILL NOT have a problem.
2. Most half marathons have a time limit (3 Hours) as do full marathons (6 Hours). I mention this because it may be something
you'll want to take into consideration. I did my first half in 2:32:49, which is an 11:30 pace. You'll need to walk at a pace
of about 13:00 to finish in under 3:00. I will say that some "speed walkers" finished well ahead of me.
3. Find a good pair of shoes and a good pair of socks. It is impossible for me to overstate the importance of this. Although you
plan to walk, I would still go ahead and get a pair of running shoes since they'll be more comfortable in the long run (no pun
intended). As for socks, STAY AWAY FROM 100% COTTON! They will stretch as your feet sweat and bunch up- a blister disaster waiting
to happen. Nothing will kill your motivation and ambition quicker than a blister. The New Balance 992 is an excellent shoe for us "Bigger" runners, and I suspect it would work for you as well. Thorlo Medium cushion socks are what I personally use because with them I've never, ever gotten a blister.
4. STICK WITH IT AND DON'T QUIT!!!! As your training progresses, you're going to notice very quick and obvious spikes in your
ability as the weight comes of. I'm running a half-marathon next weekend and I'm about 207. I should be able to finish sometime
between 1:55 and 2:05. If I were running at 215 or more, I would probably not be able to finish quicker than 2:15. The point is, by October, if enough weight has come of, you could absolutely be jogging the 13.1 miles of the half. You may surprise yourself!
5. Do you have someone who might be interested in running with you? I'm also training right now for another Ultra-marathon in May,
and I do my long weekend runs with a buddy of mine who is also doing it. It makes all the difference in the world when you're 18 miles into a 25 mile run and have someone there to help keep you motivated and going. Running is 90% mental. The other half is physical! :)
Here's the link to Hal's website. His plans are tops! Best of luck to you!
http://www.halhigdon.com/marathon/Mar00index.htmOh yea, one more thing I forgot to mention. www.runnerslog.com is an absolutely fantastic free site for keeping track of your mileage and whatnot. It's worth mentioning because, after about 2 months of this, you'll look back at your totals, see all those miles you've covered, and really start to feel like you're progressing. I ran 52 miles last week. I feel like crap right now, but just knowing that I did that makes me ready and motivated to top it. Again, running is as much about motivation than anything else. Also, get an MP3 player. Music makes the long miles seems a wee bit shorter.
