Dorset runner Peter Roper set a new course record as he won the Cornish Classic quarter ultra-marathon.
Roper completed the 44 mile race along the Cornish coastal path in six hours and 33 minutes, beating the previous record by over 45 minutes.
More than 320 runners took part in the ultra-marathon between Lizard Point and Land's End.
Newquay's Rob Burnham finished in second, while third place went to Hampshire's Warwick Gooch.
Burnham said: "The cooler conditions meant I could faster and remain cool.
"I like the journey aspect of this event, travelling uneder my own steam from Lizard Point to Land's Ends."
The first woman to finish was Helston's Nicky Taylor, crossing the line in eight hours and seven minutes, ahead of Sarah Kenworthy and Claire Akin-Smith.
