‘Stay in your lane’: Experts urge against following running influencer advice

A woman checks in with her phone at various intervals along her 30-kilometre run route.

As the video flashes back it shows her getting ready, putting on her running belt and shoes.

On another account, a man speaks directly to the camera explaining what his next race will be. He’s training for an ultramarathon where he’ll try run for days around a loop course, until there’s no one left standing.
