Lost weight and the 10K

Just a note:  Last year I came close to dying twice and in the process of getting well lost 45 pounds in 6 weeks. I don't recommend the method used. But I've pretty well kept it off and a few weeks ago actually did the Austin Cap 10. It's a 10K. I actually did it. I now walk (fast) 3 to 4.5 miles a day and feel great.
