Jim Clark won the race in extremely wet and rainy conditions. After starting eighth on the grid Clark passed all of the cars in front of him, including early leader Graham Hill. About 17 laps into the race, with the rain coming down harder than ever, Clark had not only lapped the entire field except for Bruce McLaren, but he was almost five minutes ahead of McLaren and his Cooper. This would be the first of 7 victories for Clark and Team Lotus that year.
