The data from my 7 years of running is below. 2003-2005 are estimates. I started running in 2002 but don't really count that since I barely ran (probably less than 100 all year) and I was not really a "runner" until after my open heart surgery in Oct 2002.
I still have one more run for 2009! It won't be 13 miles though so looks like I won't quite match my 2008 number. Interesting that the numbers over the last 2 years are so close. I'll probably end up with 811-812 for 2009 and one of my goals for 2010 is to top 1000 (again). It's going to be a hard-fought final run of 2009 since it's raining hard and only 38 degrees (probably colder with the wind!)
