Lubbock turned out despite an unseasonably chilly morning to bounce around at the craziest fun run around, the Insane Inflatable 5K.

It was so cold in Lubbock Saturday morning (April 2) that there was actually a fine layer of frost on the Insane Inflatable 5K's opening slide. This led to a very cold, but very fun surprise for the runners in the opening wave at 8:30 a.m. The runners didn't need coffee to wake them up; the icy slide did that just fine.

You can see more than 200 pictures from the race, including some fun costumes, action shots and runners showing off their victory medals after completing the Insane Inflatable 5K, in the photo gallery above.
