If the distance and difficulty of ŷڱƵ’s many organized bicycling events is any indication, a flat, 100-mile bicycle ride is not, for many riders, quite tough enough. That’s one reason the 11th annual Buffalo Bicycle Classic’s longest route will go farther and climb higher than any of the event’s courses so far. The “Buff Epic” will span 110 miles and ascend a total of 6,250 feet. It retraces much of the most mountainous section of Stage 6 of the 2012 USA Pro Cycling Challenge.
