Starting all the way back in 1923, the Jack Pine Endurance Run has always been one of the toughest off road races in the United States. Originally a three day 800 mile race, they have since scaled back to a mere 500 mile course over two days. It's amazing to see pictures of Knucklehead and Panheads crossing rivers, riding through mud, deep sand and over hills, often with sidecars attached.
