As for today, 10/7/03, I'm at 1833.05, which puts me in the middle of stage 17. I'm a little under 300 miles from finishing and I have a century ride this Saturday, so I'm feeling pretty confident about completing this challenge.
An additional bonus: I just hit 5000 miles for the year on Saturday (10/4). At the current pace, I think I can get close to 6500 for the year... which would totally blow away the 3500 miles I had last year.
