Sommernattsløpet Trondheim is a June street race held in Trondheim, offering 5 km and 10 km distances on asphalt. The 5 km race begins in the evening. The 10 km race is divided into two waves according to expected finish times, with faster runners starting first and those anticipating a finish time over 50 minutes starting later. This arrangement provides a summer-night atmosphere distinct from a typical daytime road race.
The course is flat and fast, designed with minimal elevation gain, making it suitable for runners aiming for a personal best as well as those seeking a short summer run within the city. Springtime Event AS organizes this Trondheim event as part of the Sommernattsløpet series. The organizer describes it as the summer's main running event, encouraging participants to trade dress shoes for running shoes at sunset.
