>>184190Fjällräven Classic is a trekking event where people from all around the world walk the last part of the swedish kungsleden, the stretch is 110 kilometer. Around 3000 people participate each year. The cost is approx. 200 dollars but then you get food supplied during the walk (it's entirely free to walk the hike any day of year).
So you'll meet like minded people who like the outdoors basically. The attitude is very friendly and it's not unlikely that you'll end up with new friends.
Next year it will be 10 years since they started, I dont know if they plan anything extra.
