Forty hockey players will skate for more than 10 days (248 hours) in an attempt to break the record for longest marathon hockey game ever played.
The Hockey Marathon puck dropped Sunday at the Chestermere Recreation Centre outside Calgary and will run through May 14.
Players are currently taking the ice in rotations of four and six hours, Global News reported.
The current record, held by many of those currently involved in the attempt, stands at 246 hours and 2 minutes.
The group hopes to raise $2 million in support of Alberta Children's Hospital, Alberta flood relief and Samuel’s Ride for Rescue.
"The kids get you through the game," participant and organizing chair Alex Halat told Global.
The Guinness Book of World Records states that the players can’t leave the venue, which means they’ll eat, sleep, and live in the arena for the duration of the two-week stretch.
Considering the strenuous and daunting task at hand, Halat says it’s the least they can do for children who suffer from serious illness.
This two-week marathon is certain to be both physically and mentally demanding, putting lengthy NHL games into context.
According to Collections Canada, the longest game in NHL history was played in 1936 when the Montreal Canadiens faced the Detroit Red Wings for 176 minutes.
The Red Wings ended up scoring and winning in the sixth overtime.
