"In Bolivia's main city, La Paz, the BBC's Mattia Cabitza was engulfed by a sea of young people taking part in a marathon, and the usually congested streets were instead occupied by street artists and other performers.
"Exercise instructors taught tai-chi to passers-by while some Bolivians were seen dressed up as zebras, playing hopscotch in the road, Reuters reports."
