Bol d'Or

The Bol d’Or is a 24-hour motorcycle endurance race, held annually in France. The riding of each bike is now shared by a team of three riders.

The Bol d’Or, first organized by Eugene Mauve, was a race for motorcycles, and automobiles limited to 1100cc engine capacity (in the 1950s the limit was raised to 1500cc, and later to 2000cc). To-day, the Bol d’Or is exclusively a race for motorcycles, although there are a number of side "attractions", such as races for amateur riders and for classic bikes.

Prior to 1953 only one rider per machine was permitted. The record holder with seven victories, French Gustave Lefèvre, won with an average speed of 107 kilometers/hour riding his Norton Manx for the whole 24 hours. From 1954 to 1977 the teams comprised two riders, and then, in the interests of safety, this was increased to three.

Until 1970 the race was held at various circuits, mainly Linas-Montlhéry and Saint-Germain-en-Laye. From 1971 to 1977 the Bol d’Or was held at the shorter Le Mans Bugatti circuit, which excludes the Mulsanne straight. For the next 22 years the event took place at Paul Ricard, after which it moved to Magny-Cours. When the race left Le Mans the 24 Heures du Mans was established, so that when the Bol d'Or returned to Le Mans, there were for a time two annual 24-hour motorcycle endurance events on the Bugatti circuit. Until 2015, the Bol d’Or was held in the spring, while the 24 Heures du Mans was in the early September slot formerly used by the Bol d’Or. In 2016 things changed again: the "24 Heures du Mans" moved to the spring, while the Bol d’Or moved to Circuit Paul Ricard In September.

24-hour motorcycle endurance racing has a strong Francophone base, with the three main events held in France (Le Mans & Magny-Cours) and French-speaking Belgium (Spa-Francorchamps), and the most successful teams and riders are French. In 1970, 1971 and 1992 all-British teams of riders won the races. British rider Terry Rymer has had consistent results. In the 1970s the competitors included Phil Read and Neil Tuxworth, who later headed Honda Racing UK, additionally the Mead & Tomkinson racing team fielded "Nessie", a revolutionary bike with hub-center steering.
