Unfortunately, I didn't have the time this week to get outside of Madrid, but I've gone all over the city. Last night, I crossed the city and spent time in Casa del Campo (>1hr away by metro) playing Catan with friends. In total, I've spent 11 hours on the metro this week.
Syracuse, NY -> Málaga (Spain) -> Granada -> Madrid -> Salamanca. The flight from Syracuse to Málaga alone was over 3700 miles, so I'm pretty certain we're over 4000 miles total (maybe even up to 4300 miles?).
By bus and by metro.
The Thyssen-Bornemi and Reina Sofia museums. Both had absolutely massive galleries, and I had to return two other days to see the Reina Sofia in full!
Myself and some friends have made plans to visit Porto, Portugal.
