When people stopped getting track time when it rained, and the event was looking like a doomed flop, the event organizer decided to change the rules, and force a wet lap. Now racers have to practice wet laps to win the points and championship

During a Gridlife track day at the Ohio course, one of three such events held across the Midwest each year, the weather didn’t cooperate; a downpour made some of the more serious, record-seeking drivers hesitant to hit the tarmac.

The solution? Invent a wet lap record. “We’re in a unique position where we can make adjustments like that because we’re right on the edge of ‘pro’ and ‘fun.’ If we became a completely pro event, the ability to do an audible like that decreases; it becomes something people get upset about. The wet lap times—they’re still not official in any capacity, but we are tracking them—was more about ‘let’s see what we can all do in the wet! Let’s make lemonade!’”
