We runners have a complicated relationship with portable toilets. We’re happy to see them before (and sometimes during and often after) a race, especially when we’ve been shot-gunning liquids and glucose. But that minute-plus (on average) we spend in their odiferous confines tends to yield some memorable-and-not-in-a-good-way moments. However, instead of shaking your fist at them, we suggest cutting the portable toilet some slack. Everything from the mysterious blue liquid to the height of the drop to the placement of the urinal has been studied and calibrated to make the best of a crappy situation. Which intrigued us—there’s a lot more to these things than we thought.
