Terrence Concannon, a 24-year-old man who ran the 2026 Boston Marathon barefoot, trained for the race in just 40 days and finished the 26.2 mile race in 03:57:23. Despite initially feeling unwell, Concannon has since recovered and is feeling great. The decision to run the race without shoes led to increased interest in spectators, with some reporting seeing him as "some random man" and his number being obscured.
