What doesn’t kill you makes stronger, right? And you know what, that’s not a bad mantra to help carry you through these rough and tough times. Maybe it’s time we all toughened ourselves up a bit, to test ourselves, to see exactly what each one of us is made of. And that’s what we’ve tried to do with this year’s Summer Guide.

It’s also about pain and suffering. It’s about feats of endurance. Or at least that’s what the Italian Ice Chowdown is about. And the Lowcountry Smoothie Slurp. And the Battery Bladder Bust. Read on. If you really want to revel in the schedenfraude, we’ve got videos of each one of the challenges.
