Baseball is for pantywaists. Football is played by the enfeebled. Hockey is a eunuch convention on ice. You want real sports? Try pushing a sled filled with weights until you vomit. It’s known as “the prowler,” and it’s just one of the grueling events at Next Level Games, a sort of strongman Olympics at Watson Park (Seventh Street and Tennessee, in Lawrence). More than 100 men and women from around the country pull trucks, flip tractor tires and scale obstacle courses in this second annual gathering of the brawny. Competition starts at 9 a.m. and runs all day, and it’s free to the public. The prowler really does make some people throw up from exhaustion, so maybe bring a poncho.
