Rio Haryanto is an Indonesian Formula One driver who is participating in the Canadian Grand Prix while also observing Ramadan which requires him not to eat or drink from dawn until sunset during the holy month which started on June 6th.
“Rio has been fasting this week but the team and his [doctor] will decide what to do on Sunday,” said his manager Piers Hunnisett. “It’s a long race and there is a worry about dehydration. Drivers lose a lot of body fluid during a race and we don’t want him losing concentration when he is driving at 350kph or whatever it may be. It’s more of a safety issue. He has been following his faith in Montreal this week but we will see what the advice of the team doctors is.”
