Bowland's Sam Harrison won the 3-mile Jubilee Plunge race from the summit of Moel Arthur to Llangynhafal, but it was a close finish with just 10 seconds separating the first four finishers.
As expected, the recent rain made conditions underfoot very tricky and several runners took a tumble in the mud.
