Ahvenisto Race Circuit is a unique motorsport facility located in the city of Hämeenlinna in southern Finland. Construction of the circuit was finished on July 15, 1967. A course with an unusual figure-of-eight design was penned by engineer Mikko Köppä, who needed the crossover in order to cram in as much track as possible in a small space. The track is 2.840 kilometers (1.765 miles) long and runs in a clockwise direction. Like the famous Suzuka circuit in Japan, Ahvenisto features a bridge where the track crosses over itself.

The circuit's main straight measures 0.280 kilometers (0.174 miles) in length, and the track width varies between 9 and 17 meters (30 and 56 feet). The facility features a total elevation change of 32 meters (105 feet), adding to the technical challenge. The official lap record stands at 1:13.226 and was achieved by Marko Nevalainen in a Formula Three car on September 16, 2000. Notably, 1982 Formula One World Champion Keke Rosberg managed an unofficial lap record of 1:11.000 during his 1984 demonstration run in a Williams FW08C Formula 1 car. The circuit's distinctive figure-of-eight layout and technical characteristics make it a unique and challenging venue in the Nordic motorsport landscape.
