Staying in Europe, today’s track can be found in Bulgaria. Vassil Levski National Stadion is the largest stadium in the country, with a seating capacity of just over 43,000. It was originally built in 1953, but has been renovated several times since then. The most recent time was just last year. Besides being used for athletics and soccer, it has also be the site of some huge concerts. While it’s hard to tell from the photo, this is a nice looking facility.
