Fibs, I'm a little concerned here...this is why:

I too had never been able to run. Then I got my thyroid medicine, and felt so good I just couldn't stop running! I prepared for the Kentucky Derby Mini Marathon (half marathon) over a period of two years. The entire last year I ran 3 miles three times a week and then six miles on the weekend. Prior to the race, about two weeks apart, I ran 8 miles and 10 miles. All this to say -- it was probably not enough preparation! I finished the 13.1 miles in 2 hours and 45 minutes (I think). At least I got the T-shirt and bragging rights for a lifetime, but...for a serious jogger, longer runs would have been better preparation. And I'm concerned you don't have much time left to prepare. Just enjoy this one, and if you really like running, then work for next year.

Advice I received:

1. Don't run on uneven roads.

2. Get good shoes.

3. Build a consistent base of shorter runs (3 miles, often).

4. Don't forget some long runs

5. If you're concerned with speed, try the running exercises you'll find in a good runner's magazine.

6. Don't damage your knees with too much downhill work.

7. If uphill is hard, try zig-zagging.

8. In races, don't try to keep up with the "rabbits"!

Above all, enjoy your preparation. I really looked forward to my long runs through a beautiful wooded area, music in my earphones, and a GatorAid (salty drink) reward after it was over. My second wind didn't kick in until 1 1/2 miles, and I knew exactly where that was.

Let me know when the big day is. I'll be there. (in spirit, of course, holding a big sign at the 10-mile marker)
