Moving from the track to the living room, many athletes around the world are doing their bit to boost public health during the coronavirus pandemic.
There's been an explosion of athletes offering free online fitness classes and tips to an audience isolated at home.
It helps others keep fit, and especially for sports like track and field, it's a way to stay relevant in a year without the Olympics.
"The onus is all now on the parents and for kids you're stuck in whatever space you've got at home," former marathon world record holder Paula Radcliffe, who is preparing an upcoming online class for World Athletics, told The Associated Press.
"So it was just trying to make that a fun way to get everybody active together and try to restore a little bit of normality."
In Germany, world long jump champion Malaika Mihambo led an after-school sports club for young children. Now she's taken it online, with daily German-language YouTube workouts packed with motivational chat for the kids she calls her "world champions."
"If I can make my little contribution to putting a bit of structure in their everyday lives in this time, to make them enthusiastic about sport, then I'm happy to do that."
