Toulouse Trip - July 6 to July 9

Bonjour! My wife, 14 year old son, and I will be staying in Toulouse for a few days in early July. My wife has already set up a local walking tour, but I was curious if anyone had can’t miss advice on things to do during our stay? In particular, I’d love to see local sports or culture (though I know Sunday through Wednesday typically isn’t the best option for live sports). Should we rent a car and go south to the coast? Any other tips for things a 14 year old boy would especially like?

Thanks in advance!
