I just rode the MGT (April 2011) and have submitted an updated detailed description to TrailLink.com
Briefly, first two miles are paved (St. Andrews to Sewanee). For ~1/2 mile through Sewannee it is difficult to follow thru a parking lot and the highway shoulder encroachment, but then it becomes recognizable single track. Be prepared for the next 1/2 mile. A creek overtakes the trail (10 feet wide, 2-10" deep). Creek then "departs" and for the next 5 miles, the trail is a steep downgrade, very rough, rocky, washouts, etc. But a gorgeous ride! About 2 miles from the Cowan end, the MGT parallels an active rail line for 1/2 mile , and then merges with it. The last 1.5 miles you ride on tennis ball sized ballast of the active line. That is why it is impossible to find the trailhead at the Cowan end!
If only funds were available for surface and drainage improvement and separation from the active rail line on the Cowan end, this would be a gem of a trail. I still had a fun, but challenging ride! [I'm 67 yrs old.]

"This is a great paved trail from St. Andrews to Sewanee through the hard work of several folks. No motor vehicles are on the paved part. The section between Sewanee and Cowan is a jeep trail, but it's a beautiful hike down to the bottom of the mountain. Efforts are underway to extend the trail from St. Andrews to Monteagle, TN."
