Fanahytten Opp is a 7.2 km uphill race at Fanahytten in Vestland, Norway. It is a traditional end-of-season event for Region Vest, held in late September.
The race has been run for nearly fifty editions, so it is a fixture on the local calendar. After the climb, runners gather for a cake party, and anyone fast enough to beat the course record can win a cash prize.
