did the 47 mile loop from my house over to the natchez trace on my mtb, took 3 hrs, 10 minutes. Highlight of the day was a few minutes after the crest of the 3 mile long climb from hwy 100 up onto the trace a guy came huffing and puffing up next to me on a road bike and said "Man, I've been trying to catch up to you forever!" - "since when?" I asked "hwy 100- you're flying on that thing, what is it, a hybrid?" "nah... just a mountain bike" - which was great, until I learned that it was his second day out riding. Noticing his calves that looked like my thighs, I asked if he was a runner, which he was. He said it got boring and he wanted to try something new... as we parted @ his 10 mile mark I suggested he go easy in the beginning, just like he probably knew from running, and he agreed
