I have done the 100K twice. Great event, but hard. My LHT was not the right bike for the ride (very heavy), but I managed. I was a four-year Deerfield Academy boy ('79-'83), so returning to the town was like a homecoming. Stopped there in June of this year for two nights during a self-contained tour from St. Albans, VT to Philly. Attended my 35th reunion.
