It’s time for another Mud Run! What, you don’t know what the Mud Run is?

It’s a boot camp-style fund raiser. And it’s all for a good cause.

The San Bernardino’s Sheriff’s department is holding their 7th Mud Run tomorrow, starting at 8 a.m. It’s a 5K run for adults, and  1K run for kids.

Money raised goes to charity and for the Sheriff’s department’s athletic events.

Already, 1800 volunteer have signed up to run…with room and hopes for 700 more.

Did we mention it’s a run though a muddy course?

You will have fun but you will get muddy! Very muddy. It’s a tough obstacle course…and the mud doesn’t help!

There are rinse stations at the end of the course. But as Greg Mills reports for CBS2, expect to find mud in places you never expected to find mud…ever!
