24 Heures La Tuque
From Openwaterpedia
24 Heures La Tuque or the La Tuque 24 Hour Marathon Swim was a 24-hour 2-person professional marathon swimming relay held in the 1960s and 1970s.
24 Heures La Tuque was a non-stop relay with up to 20 two-person teams that ran from 3 p.m. Saturday to 3 p.m. Sunday. The race was staged in an egg-shaped Lac Louis in Quebec, Canada. The course was a one-third of a mile plus 11 feet that paralleled the shore so crowds of thousands cheered on the professional marathon swimmers day and night.
Some of the greatest marathon swimmers of that era competed in the race.
