Ride too slow and you’re in the pollution too long. Ride too fast and you’ll suck down a lot of extra air. But there’s a sweet spot, says science.
In a recent study, a researcher calculated exactly how fast to travel to limit exposure to pollution. Around seven to 12 miles an hour on a bike. One to four miles an hour if you’re walking. If you go about six miles per hour faster on your bike, you can breathe in about twice as much bad air.
