Trønder-Østløpet is a 5 km and 10 km road race in Hommelvik, held in June and arranged there since 2016. It starts and finishes at Øya Stadion, giving the event a stadium base rather than a point-to-point setup.
The course is officially measured by avKondisLøypa and is built for steady pace: little elevation change, long straight sections, and room to run fast. Many runners use it as a final sharpener before St. Olavsloppet, so it draws people looking to check their form as much as people chasing a quick local race.
