I had to bow out. I woke up on my birthday (may 19th) and my back just siezed up on me. It got bad enough I am not even sure how I got out of bed in the mornings because I couldn't even roll over. Pretty much had to hjet get my legs to the side of the bed and let gravity work for me. Got worse and worse as June approached with the worst of it being 2-3 days before the ride. Ended up bowing out, and finally, this weekend, I'm to the point where I can function at about 90-95%. Almost 100% if I take about a half hour to do some mild exercise to do whatever I am going to do. But as soon as I sit down, it locks back up on me.
So, unfortunately, I didn't ride, and haven't since April. Bending/leaning over is the worst for me right now.
