Kristinaløpet is a road race in Tønsberg, starting and finishing at the city beach on Kaldnes. Participants can choose between 5 km and 10 km distances, with an additional 5 km option for those seeking a less competitive run. The event also includes Barnas Kristinaløp, a short children's race of approximately 500 meters, and Kristinastafetten, a relay race integrated into the program. The races typically take place on a Saturday in late June, during the daytime, influencing course design around Tønsberg's central traffic and event safety considerations.
The Kaldnes course navigates streets around the waterfront and city center. The 5 km route begins near Rambergveien, goes past Hotell Klubben, and turns after the Slottsfjelltunnel. Its flat terrain is suitable for both speed-focused runners and those preferring a simple city race. Kristinastafetten divides 5 km into five segments, ranging from about 400 to 1800 meters, making it accessible for diverse teams including workplaces, families, and friends. A specific instruction for participants: staying within the marked start and finish area is necessary for the timing system to record their run.
