Hmmm. I'm more than a little concerned with the discussion about 12 hour riding days. If this is the case, I'll have to regretfully withdraw from the event, which also effects Mexican.
At my age I simply don't ride long days like that anymore, which is one of the reasons that I normally ride solo or with a close friend who rides as I do. I've ridden throughout the US and Canada and love to take my time, take in the scenery and smell the roses so to speak, taking many pictures along the way. 8 hours and about 350 miles for me is about right.
