If you haven't signed up for the Insane Inflatable 5K yet, you'd be insane not to do it before March 10!

With the promo code above, you can instantly knock $15 off the registration fees for the Saturday, March 25 race at Ascarate Park.

THIS FLASH SALE STARTS ON MONDAY, MARCH 6 AND ENDS AT 11:59 P.M. ON FRIDAY, MARCH 10.

This will be the your last chance to get your registration at a price this low -- unless, of course, you also sign up for your chance to win a FREE registration as a member of our VIP program.

I mean, if you insist, we'll let you pay full price for El Paso's coolest 5K walk/run event. It's good for all ages (as long as you're 42 inches or taller). It's an incredible workout, and it's just plain fun!
