This chap in a Santa hat has got all muddy for the annual Maldon Mud Race.
More than 200 people took part in the event in Maldon, Essex, on Sunday.
Competitors had to cross the mouth of the River Blackwater at low tide - a distance of nearly 500m.
It's all for charity, and organisers say they raise tens of thousands of pounds each year.
But this penguin looks like he just wants it all to be over!
