The oldest annual marathon in Europe was established in 1924 in Košice, present-day Slovakia. The same year Boston Bruins became the first team from USA to enter NHL. Interestingly, first annual marathon in the world was in 1897, Boston, just one year after the introduction of the discipline at the Olympics. That same year Boston was also the first city in USA to get metro, The Tremont Street Subway.
Ah yes, and current captain of Boston Bruins is a Slovak Zdeno Chara.
