It's an annual 7-day event that took place for the 50th time this year. Official "motto": Walk for 4 days, party for 7 days.
What the hell does that mean?
Basically, around 45,000 people gather in the city to walk a certain distance every day for 4 days in a row. It's the biggest walking event in the world.
What are the distances?
30 km per day for kids
40 km per day for women
50 km per day for men (That's more than a marathon! - 4 days in a row)
The walk is done always on the same route every day in the 4 cardinal points - north, east, south, and west, always crossing through the city center.
What's the point?
In short, it's a tradition. Besides the walking, partying is of utmost priority for everyone in the city for the 7 days that are around the festival. Live music is played on 40 stages around the city. You can hear everything from EDM, Latin, soul, to jazz. Food trucks and bars are open everywhere, making sure everybody is well fed and hydrated.
Full disclosure ... I did walk, but mostly from bar to bar and from stage to stage. That added up to 15 km over a couple of hours ... not bad.
