Rugged Run is a 5k obstacle course filled with water and mud. On Mar. 23, the course was held at the Alameda County Fairgrounds in Pleasanton. There was more than a thousand people that raced competitively and for fun. Runners have to crawl through mud pits, swing across monkey bars and climb blown-up obstacles.
Correction: In a former version, the date said May 25. The correct date is Mar. 23.
