The Vermont Gran Fondo (VTGF) was born from a famous bucket-list epic 4-gap ride known by the locals as the LAMB ride. LAMB comes from the names of 4 gaps (Lincoln Gap, Appalachian Gap, Middlebury Gap, and Brandon Gap) which, when combined into a single ride, can easily top 100 miles and over 10,000 feet.
