Clark won the 1963 Belgian Grand Prix at Spa-Francorchamps in extremely foggy and rainy conditions. After starting eighth on the grid, he 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 lapped the entire field except for Bruce McLaren, and was almost five minutes ahead of McLaren and his Cooper. This would be the first of seven victories for Clark and Team Lotus that year.
