Las Vegas, NV (KTNV) -- The rain held off on Saturday so people could enjoy a morning run that included a lot of obstacles.
It was not like any other 5K run you've seen. It happened at Sam Boyd Stadium.
There were large obstacles like inflatable ramps that runners had to work their way over.
Here's the catch on this popular 5K: It's not a race. No one is timed and there is no official winner, it's all just for fun.
