I'm kind of in the same boat as you. I normally do the "full" Horsey Hundred over Memorial Day weekend. Last year, that was 180 miles over two days. I felt great. Mr. Silver (from TE) even burned up the road on Sunday's ride.

This year, I've decided to do a shorter route on Saturday and to play Sunday by ear. I just haven't able to train as much between travel and bad weather. Plus, I haven't gotten the fit on my new bike quite right just yet. It's been kind of a bummer. I'm making progress, but it's been a bit of trial and error.

After responding to your post last night, I actually did a search on Mapquest to figure out how far away Tulsa is from Indianapolis! I think it was 640 odd miles. That's doable, right?

Be good and have a great ride!
