Thousands of mud-covered people will roam The Grove in Sanger, as the Mud Factor 5K debuts in the Central Valley on Sunday.
More than 3,000 runners have signed up for the mud run, according to marketing director David Carpenter.
A portion of the proceeds will benefit Children's Hospital Central California.
Mud Factor, the Rocklin-based mud run company, prides itself on being not-so-serious about the running and more serious about the fun.
The 3.1-mile obstacle course will feature various mud pits and a 12-foot wall with a rope on one side and ladder on the other, and ends with a cargo net climb.
Participants will start in waves released every 30 minutes, with the first starting at 10:30 a.m.
The Mud Factor Kids race starts at 9 a.m. on a condensed version of the course for children ages 4 to 13. Parents will need to submit a waiver for their child to participate.
Online registration starts at $55 and closes at midnight Thursday. Details and links to promotions and discount codes can be found at www.mudfactor.com.
On-site registration will be available the morning of the race, though Carpenter said those participants may not be guaranteed the free goodies that come with pre-registering. Spectators are welcome but must pay a $10 on-site parking fee.
It's not the first mud run at The Grove. The Mud N' Blood Zombie Run returns June 7.
** Woodward Park will be overrun by children Saturday for the Carnival Kids Course. The race mimics a color run with colored corn-starch blasts along with rides, bounce houses and games. The race is open to children ages 4 to 13. Details: www.carnivalkidscourse.com.
