European Le Mans - 4 Hours of Le Castellet

The 4 Hours of Le Castellet stands as a major endurance race on the European Le Mans Series calendar. Circuit Paul Ricard hosts this competition, which serves as the second round of the ELMS season. Teams and drivers use this race as essential preparation before the 24 Hours of Le Mans, testing their strategies and car setups on one of France's most versatile racing circuits.

Circuit Paul Ricard Overview

Circuit Paul Ricard sits in Le Castellet, located in the Var department of southern France near Marseille. The circuit opened in 1970 after French pastis magnate Paul Ricard built the facility in 1969. The track earned recognition as one of the most modern motorsport facilities upon its opening and again after renovations in the early 2000s.

The circuit features a modular design that offers up to 247 possible track configurations. The layout typically used for ELMS events measures 5.821 km and includes 13 turns. The famous Mistral Straight stretches 1.8 km and usually incorporates a chicane for endurance racing events. This long straight plays a crucial role in race strategies as drivers reach high top speeds.

Circuit Paul Ricard pioneered innovative safety features with its distinctive asphalt runoff zones. These areas use "blue" and more abrasive "red" surfaces that slow cars safely without traditional gravel traps. The venue can accommodate over 90,000 spectators and has hosted numerous prestigious events, including 14 Formula 1 French Grands Prix, Bol d'Or motorcycle endurance races, and World Championship Moto Grands Prix.
