oh, yes. It's a road race I plan to enter. They have the options for 25, 50 and 100 miles. Last spring, I was planning on the 100, but after a really hard winter (lots of sickness in the house), I'm paring it down to something I think I could handle in 4 or 5 moths time. Who knows? Maybe by the time I get there, I'll feel ready for more!
