2010 Quadruple Dipsea

Leor Pantilat became the third man ever to run under four hours in the Quadruple Dipsea, and Caren Spore broke the current course record, in the race's 28th running on November 26, 2010.

Pantilat, 26, ran the first two legs in under 1:48, perhaps the fastest first half of a Quad ever. He closed with laps of 61 and 65 minutes to finish in 3:54:29. Only Carl Andersen (three times) and Erik Skaggs (twice) had broken four hours before, with Skaggs' 3:52:16 the all-time fastest. Gary Gellin was runner-up, eight minutes behind.

Spore, 42, put up splits of 64, 68, 71, and 75 minutes to finish in 4:38:33. This broke Beth Vitalis' modern course record by 36 seconds. Kathy D'Onofrio's 4:32:16 from 1987, when shortcuts were permitted, remains the fast Quad by a woman. Kara Henry was a distant second place, arriving 37 minutes after Spore.

Larry Castano finished for a 25th consecutive time. Castano runs with only one lung, the other having collapsed.

Some rain fell during the race, after rain earlier in the week, leading to extremely muddy and slippery trail conditions. Even Pantilat fell three times. Only 201 runners finished, lowest since 2004.
