Tyrifjorden Rundt

Tyrifjorden Rundt is a recreational road cycling event organized by Oslo Klassikerne, beginning at Bryggetorget in Sandvika. Participants can select either a 64 km route or a 145 km route, with the event adhering to Norwegian road-cycling and safety regulations. The complete course travels from Sandvika towards Asker, Liertoppen, Tranby, Sylling, Vikersund, the Røyse peninsula, Vik, and Sollihøgda before descending to Gamle Ringeriksvei and concluding at Kirkerudbakken. The shorter route deviates after Sylling towards Sollihøgda, then merges back with the longer route towards the finish. The event is named after Tyrifjorden, Norway's fifth-largest lake by surface area.
