I love Tromsø, but just one question: What’s with all the sports shops in Tromsø? Must be over 10 (!) sports shops in a city with a bit more than 50 000 inhabitants

We just got back from Tromsø. This gateway to the Arctic has it all: cool bars, nice restaurants, culture, music scene, festivals and LOTS of sports shops! Why? It seems bizarre. What do u think?
