A Relay sprint

8 p.m. ET, May 31 updateThanks to a couple of donations today, I am now $322.20 away from hitting my goal. New to the challenge: running a mile total backward. I might not do the full mile at one time, but I'll make sure 4 laps are done running backward.

10 p.m. ET, May 31 update $172.20 to go! The generosity of others is amazing. I'd love to wake up in the morning and see my progress bar completed. Let's go!

8 a.m., June 1 update Less than 12 hours and $100 to go ...

Original post: In less than 48 hours, I will be hitting the track for Relay for Life. As part of my fundraising efforts, I made a pledge a while back to run a mile for every $50 raised, up to 10 miles.

It's a similar goal I've had in years past. Last year I upped the ante a bit and committed to run 13.1 miles on the track if I hit my goal of $1,000.

This year I had a tougher time committing to a similar goal. I needed to wait to see how I felt after Cleveland before figuring out something special when I hit the $1,000 mark.

Well, here it is ... as I write this, I am $337 away from my goal; my team -- Wimmer Chiropractic's "Cracking the Cure" -- is about $600 from it's overall goal.

So what do you say? Want me to run another half marathon in circles, all for a good cause? I'd love to do it again, but I need your help hitting my goal by Friday night.

To donate, visit my Relay page, then click on "Donate on My Behalf." (Or just go here.) Relay for Life makes it easy for anyone to donate -- the minimum is just $5.

As donations come in over the next couple of days, I will update as much as I can above. Let's make this happen!
