Asthma couldn’t prevent Nikki Guernsey from running the Triple Crown, Louisville’s trifecta of 5K, 10K and 10-mile races, but nothing slows her down like an air quality alert day.
“It feels like a suffocating blanket, despite using my rescue inhaler,” she said of trying to run outside when ozone levels are high.
Instead, she trains indoors on those days.
Guernsey belongs to a group of area residents who have to take special care on air quality alert days like today.
They include people with respiratory conditions and individuals in two age groups, children and the elderly, said Dr. Gerald Lee, an assistant professor in the University of Louisville’s Department of Pediatrics.
