(CNN) -- [Updated 3:30 p.m. ET, Monday, May 30] The "pig" above is running the Gothenburg Half Marathon in Gothenburg, Sweden.

The race, known as Göteborgsvarvet in Sweden, took place May 21 and is one of the most popular half marathons in the world. More than 59,000 runners signed up to compete in the race, which has been held every year since 1980.

This year's winners were a couple of Kenyans: Albert Kiplagat Matebor finished first on the men's side with a time of 1 hour, 52 seconds, and Joyce Chepkirui finished first for the women at 1 hour, 9 minutes and 4 seconds. Sorry, I have no idea where the pig finished or if the pig finished at all.

Gothenburg, a seaport on Sweden's southwestern coast, is the country's second-largest city behind capital city Stockholm. According to the race website, Gothenburg "offers the charm of a small town and the opportunities of a big city with museums, a fantastic amusement park, good food and a lot of different activities."

The only person to correctly answer this week's photo challenge was "TheStreak," who added that "elaborate costumes have become quite common" for the race.

[Original post] Do you know where this photo was taken?

If you think you know the answer -- or if you just want to take a wild guess -- post it in the comments area below. Later in the day, we'll reveal where the photo was taken and give credit to those who figured it out first. (The more detail, the better!)

Each Monday morning, we'll post a new photo and challenge you to tell us its origin. The photo might be related to a prominent news story or theme -- or it might just be something that caught our eye.

Good luck!
