Local emergency groups are planning the June 1 event known as Red, White and Blue Mud Run to raise money, said Le Mars Police Officer Jay King, mud run committee chairman.
"It's a 5K obstacle course with a lot of mud involved," he said. "It's going to be a physical challenge; it could be a mental challenge for a lot of people."
Mud runners may be asked to crawl through a tunnel up to their chin in mud, crawl in mud under barbed wire, run a mile through mud, drag or carry something, climb walls or hay bales, King said.
"People should train for it, it will test their endurance," King said.
Groups organizing the first-ever mud run in Le Mars include the Le Mars Police Association; Le Mars Ambulance Association; Le Mars Fire Association; Plymouth County Peace Officers Association and the Plymouth County Dive Team Association, according to King.
Some of the local emergency associations had members participate in area mud runs, he said.
Le Mars Police Officer Justin Daale came up with the idea of hosting a mud run in Le Mars, King said.
"We thought what better way than to use our emergency groups to sponsor it and to also help their associations with projects," he said.
For example, proceeds will help the Le Mars Police Association assist a group or individual with a need.
The Le Mars Police Association will also be involved with Iowa Concerns of Police Survivors (Iowa C.O.P.S.).
The group provides resources to assist in rebuilding the lives of surviving families and co-workers of law enforcement officers killed in the line of duty.
The local emergency groups plan to begin the Red, White and Blue Mud Run at 9 a.m. June 1.
"It's tentatively going to start at the Le Mars Little League fields, go north along the walking trail, across the river, south along the west side of the Floyd River to almost the airport and back across the river to where we started," King said.
Spectators will be encouraged to cheer on mud runners along the route, too.
Optimistically the local emergency associations hope to attract between 500 and 1,000 participants who are 18 years of age and older to be part of the mud run fundraiser.
"I don't see why Le Mars and the surrounding area couldn't pull that off," King said.
People may sign up as a team and prizes will be award for the best costume.
Registration is through www.allsportcentral.com at an individual entry fee of $50 until Feb. 1. After that date participants will pay an additional $10 or $60.
The fee increases to $70 on April 1 and will be $80 the day of the mud run, King said.
Information about the mud run is on Facebook at www.facebook.com/REDWHITEBLUEMUDRUN, he said.
A mud run won't be timed for the first year of the event and there aren't prizes other than for costumes.
"People get the right to say 'I did it,'" King said. "In future years we may have a timed event; it's a learning process for us."
If the drought of 2012 continues into this summer there will still be mud, he said.
"We'll make it, the Le Mars Fire Association has stated they are very good at making mud," King said.
