2019 World Record Baseball Marathon

May 2019, two teams of amateur baseball players will gather in St. Louis to attempt to break their own record of the “Longest Marathon Baseball Game” ever played. Ranging in ages from 18 to 62, the players will attempt to establish a new record of over 75 uninterrupted hours of baseball.

The game and fundraising proceeds from the event will be dedicated to St. Louis Children's Hospital.

Current Guinness World Record

The current Guinness World Record for "Longest Marathon Playing Baseball" is 74 hrs 26 min 52 sec.  The record was established in 2017 by our players.
