Sure, it's coming up Saturday, but if you haven't yet signed up for this year's Insane Inflatable 5K, you can still save some serious money on your registration!

The Insane Inflatable 5K is a way-cool, fun event for the entire family. Sure, it's an actual 5K run (which is just over 3.1 miles), but along the way, there are numerous 'obstacles' for you to run over, under, through or around.

Think of those challenges they make contestants do on 'Survivor,' but way easier-- and more fun. And here's the best part: if you use the promo code STJOHN10 when you sign up HERE, you'll save $10 on each registration!

My wife and I ran the Insane Inflatable 5K two years ago-- when it had just rained, and the course was pretty muddy-- and had a great time. And if you wondered how I got ready for the big race, check out the video below!
