The local rugby team, Benneton Treviso plays their rugby in the European Champions Cup and in the Pro12, competitions that sees them face some of the best rugby teams in Europe. I've seen Benneton Treviso play against Leicester Tigers a few years ago, and I have to say, I highly recommend doing such a trip if you're into rugby. The atmosphere is great, the city is great and it's also really close to Venice, so you can go there as well.
