The winners of the men's and women's events at the 2013 Jersey marathon both set new course records on Sunday.
Kenya's Reuben Chumba won the men's race in two hours, 24 minutes and 23 seconds, taking 19 seconds off the previous best.
France's Svetlana Pretot, 42, smashed the women's record in a time of 2:44.33, nine minutes quicker than Shona Crombie-Hicks' previous best.
Jo Meek from Tavistock in Devon, finished second in the women's race.
More than 500 runners took part, as well as thousands more in relay teams and the 3K event.
Chumba, who was second in the Guernsey marathon this year, held off a strong challenge in the late stages from last year's winner and previous record holder Thomas Abyo, with the Ethiopian finishing in second place.
"It feels really good," Chumba told BBC Radio Jersey on the finish line. "It's a fantastic marathon."
