The most popular run in Switzerland took part yesterday in Geneva.
Around 27'000 persons ran it (it's not the Sun run, but compare to Swiss population is not bad) from 6 years old till 89yo.
It's a pretty fun run and short one (4,8km for women and 7.3km for men), which egals with a fast run. Usually after the run we all say "Oh my God, I ran it too fast" but the atmosphere is so great that you forget about the pain!
