Jamasen Rodriguez, a senior at Modesto High School, completed a "lunge mile" around the Modesto Junior College track on Saturday in 25 minutes, 21 seconds. He is believed to have set a Guinness world record in the unorthodox and obscure event.
A lunge racer goes down to one knee on each step, a brutal routine that Jamasen - a member of the Modesto High track team - discovered on YouTube and started practicing in his back yard in the spring.
Jamasen kept a steady pace around the track, stopping only for a moment about the halfway mark to fling off his shirt.
