Riga Latvia marathon has a section called song alley where a massive traditional choir sing their songs of independence.
Genuinely the coolest experience of any marathon I’ve done, the marathon passes the choir and dancers twice, one is probably around mile 10 or so, then the second time while you are in the pain cave after 20 miles or so.
Almost everyone had fun running and cheering the first go by but almost everyone runner was silent the second pass through, it genuinely gave me chills and made me tear up.
Latvia has such a rich history of independence and song was a huge part of their cultural preservation. Highly recommend Riga next spring, it’s a fast course as well.
