On Saturday, Sept. 14, as many as 600 people will compete in the second annual Great ISU Ambush 5K, an obstacle race featuring mud pits, tire crawls, wall climbs and more.

According to co-organizer Zara Sivertsen, roughly 280 people are already registered in teams of four to compete in the mud run. Registration is $100 for teams through Aug. 31, and $125 until Sunday, Sept. 8. The cost of registration covers a T-shirt, water bottle and other assorted goodies for each team member.

Because the race is staggered in 15 heats (with 10 teams racing per heat) between 8:30 and 11:30 a.m., up to 150 teams of four are able to compete.

Sivertsen said registration is already closing in on organizers’ goals and numbers are increasing even more as the deadline draws nearer.

Anyone interested in registering can go to isu.edu/ambush, where they can find a link to the registration website. The event is not restricted to Idaho State students and has been advertised as far as the Boise area and Logan, Utah.

“The majority of people are from the Pocatello area,” said Sivertsen.

The race will take place on ISU’s campus, beginning at Bartz Field and concluding in the hilly area behind the Stephens Performing Arts Center.

In addition to race participants, organizers are looking for volunteers to help run the event. Those interested can contact Sivertsen and co-organizers Jordan Reed and Matt Bloxham via email at ude.usinull@hsubma.
