The annual Maldon Mud Race has taken place at Promenade Park in Maldon, Essex.
Each year competitors attempt to dash across the bed of the River Blackwater, and luckily this year the sun was out to keep the mud-racers warm.
The crazy competitors crawl through metres of sticky mud to reach the finish line before the tide comes in.
The event sees a number of competitors dressed in wacky costumes, which makes the task of crossing the finish line somewhat harder.
This year’s race saw 300 entrants competing for charities.
