Saturday March 3 saw 72 teams of food cart enthusiasts hit the streets of Portland for WW's second  Cartathlon. The food cart-focused scavenger hunt gave the teams four hours to travel around the city's best street vendors, completing challenges and taking photos, in a race to win free cart food for a year.

For those of us observing, highlights included watching competitors try to catch sesame oil-covered water balloons at Koi Fusion, and eating fried pies with no hands at Whiffies.

The final four teams then faced off in a gustatory showdown at the finish line, which saw them answering food cart trivia questions and scarfing down waffle tacos with fillings like kim chi, ham and raspberries (yes, all together) in a gloriously repulsive display.

Snaps to winning team "Dirty Ashley", which took home the grand prize, and the Sloppy Jerrys, Who Carted? and Carte Asada, which came in second, third and fourth, respectively. You can see the full results here.

Here are some happy snaps of the day, by photographers Mike Grippi and Ivan Limongan:
