If you've ever tried sprinting a marathon, you know what it feels like to play in a postseason game that goes into overtime.
If you haven't sprinted a marathon, you should check out NBC Sports' latest episode of the "Sports Uncovered" podcast. NBC Sports Philadelphia takes fans behind the scenes of Game 4 of the 2000 Eastern Conference Semifinals between the Flyers and the Pittsburgh Penguins, which took five overtimes and seven hours for Philly to earn a 2-1 win.
But the Flyers and Penguins aren't the only professional sports teams that played a seven-hour postseason game.

That epic 18-inning affair smashed the record for the longest postseason game in MLB history. And get this: Game 3 alone lasted longer than the entire 1939 World Series, a four-game New York Yankees sweep of the Cincinnati Reds that spanned seven hours and five minutes of total game play.
A few other incredible facts about Game 3, which Dodgers infielder Max Muncy mercifully ended at 3:30 a.m. ET:
-- The teams combined to use an MLB-record 18 pitchers.
-- Red Sox right-hander Nathan Eovaldi threw 97 pitches in relief, the most by a reliever in World Series history.
-- Red Sox outfielders Mookie Betts and Jackie Bradley Jr. both switched positions six times.
-- Utility man Eduardo Nunez went 2-for-4 in four plate appearances despite not entering the game until the 10th inning.
The Red Sox rallied from that debilitating loss to win the World Series in six games, while the Flyers also took their 2000 series with Pittsburgh in six games.
But if you thought Red Sox-Dodgers Game 3 was wild, wait until you hear about Flyers-Penguins Game 4.
As you'll hear in the podcast, seven hours of playoff hockey led to a crazy scene that included Pittsburgh's Mellon Arena running out of food, players receiving IV treatments and shifts lasting less than 10 seconds.
