Sudden-death overtime in pro hockey feels like the wildest, most frantic kind of sports fight, because once regulation ends with the score level in the Stanley Cup Playoffs, the usual boundaries just disappear. The whole thing can run on like forever, multiple hours, and suddenly it becomes a tough grind, where physical exhaustion and mental strain start taking turns. Over time in the National Hockey League, a few games didn’t just get written down, they turned into real endurance milestones.
The Marathon of 1936: Detroit Red Wings vs. Montreal Maroons

The longest game in NHL history happened on March 24, 1936 in a Stanley Cup Semifinal between the Detroit Red Wings and the Montreal Maroons and the score stayed locked at 0–0 through regulation, then the postseason deadlock slid into this defensive stalemate, and it kept going past five full overtime periods. By the time the sixth overtime began, the ice surface had already deteriorated pretty badly, since modern resurfacing gear wasn’t a thing yet.
The game finally wrapped up 16 minutes and 30 seconds into that sixth overtime for a total of 116 minutes and 30 seconds of overtime action. Rookie forward Mud Bruneteau got the only goal, handing Detroit a 1–0 win over Montreal goaltender Lorne Chabot. Detroit’s goalie Normie Smith was credited with about 90–92 saves, which cemented one of the most remarkable shutouts in hockey history. The physical cost was brutal; players on both sides reportedly lost a lot of body weight during the run and the Maroons later ran into financial trouble and they eventually folded in 1938.
The Easter Epic of 1987: New York Islanders vs. Washington Capitals
On April 18, 1987, the New York Islanders and Washington Capitals met in Game 7 of the Patrick Division Semifinals and that matchup picked up the name “Easter Epic,” and it’s still considered the longest Game 7 in NHL history. Regulation ended tied 2–2 after Islanders vet Bryan Trottier scored late in the third to even things up, then the teams got pushed into a quadruple-overtime marathon that stretched past midnight and into Easter Sunday morning.
Statistically, it turned into this legendary goaltending showdown. New York’s Kelly Hrudey stopped a franchise-record 73 shots, while Washington’s Bob Mason denied 54 attempts. Washington set the tempo a lot of the time, outshooting the Islanders 75–57 overall. The tie finally cracked at 8:47 of the fourth overtime when Islanders forward Pat LaFontaine fired a slapshot past Mason glove side for a 3–2 win and altogether it was 68 minutes and 47 seconds of overtime and the final buzzer sounded at 1:58 AM.
The Modern Standard: Columbus Blue Jackets vs. Tampa Bay Lightning

For the modern era the endurance benchmark came during the opening round of the 2020 Stanley Cup Playoffs and on August 11th, 2020 the Tampa Bay Lightning ran into the Columbus Blue Jackets in a five-overtime thriller that forced coaches to keep tweaking player usage, shifts and rotation patterns; the game ended after 90 minutes and 27 seconds of overtime when Brayden Point scored to give Tampa Bay a 3–2 victory.
This more recent classic also produced some standout individual marks. Columbus goaltender Joonas Korpisalo set an NHL record with 85 saves in a single playoff game and defenseman Seth Jones logged an astonishing 65 minutes and 6 seconds of ice time- a workload you hardly ever see in the modern NHL anymore. Even with advanced training methods and modern sports science, the takeaway doesn’t really change: sudden-death overtime still hands out one of the biggest endurance trials in all of professional sports.
