The Tom Bamford Lancaster Classic was a professional road bicycle race held in late May or early June between 1992 and 2007 in Lancaster, Pennsylvania, USA. With the exception of the first race, which was 57.6 miles (92.7 km), the Lancaster Classic covered about 91 miles (146 km). Due to the "short, winding hills," it had a very low attrition rate, with 37% of starters finishing the race on average. 2003's 14% attrition was lower than that of the 2021 Tour de France, in which 23% of starters finished.
