Lion,
Are you saying that you run Springfield to London, r/t? If so, that is some serious biking.
I've only once run YS to London r/t, and it kicked my butt.
I often ride my MTB into Springfield and then take the northern trails: one up to Urbana, the other out to Buck Creek. Ever ride them?
I like the Buck Creek run the best; it's even prettier than the southern runs out of YS, but I hate cutting through Springfield because there is always glass on the trail through town so I refuse to ride anything lighter than the bike with the heaviest tread, plus gator (tuffy) strip (23c racing tires wouldn't survive 5 minutes on that city-trail).
