Berwick Run for The Diamonds is a nine-mile foot race starting and ending on Market Street in downtown Berwick, Pennsylvania.
The course has remained essentially unchanged since 1908, running up a very challenging hill and through the countryside of Summerhill.
The race starts on Market Street in Berwick and goes north along that street for about a mile before turning onto Summerhill Road, which becomes Foundryville Road as it goes through the municipality of Foundryville.
After cresting the hill around mile 3.5, it heads mostly downhill to the halfway point where it turns onto Kachinka Hollow Road and continues descending to Martzville Road at mile 7.
However, from 1946 to 1954, the race finished at Crispin Field in Berwick.
