As the mercury rose late morning Wednesday on an unseasonably mild December day, so, too, did the traffic on Mark Sather Trail, a popular public path with sweeping views of White Bear Lake.
Dog walkers, solo walkers, power walkers, runners, the occasional bicyclist — all made their way at various speeds in the warming sunshine.
On this day, in the age of COVID-19, what they were doing wasn't as interesting as to how they were doing it. How did people comply with social distancing guidelines when they encountered one another on the trail, recommendations that call for a buffer of 6 feet or more?
University of Minnesota researchers are leading a national study and have been keeping tabs on and off since spring. Some of what they find could inform trail management and planning in years to come. Teams of observers are documenting compliance on public paths like the Sather Trail as millions of Americans seek routine and refuge during the pandemic.
Researchers have seen more than 10,000 encounters — in which trail users came together — across 14 trails in six states. In addition to Sather Trail, Minnesota crews have collected data at Lake of the Isles and Wedgewood Park Trail in Mahtomedi. Some takaways to date about trail users' behavior:
• More than half of trail users didn't allow enough physical distance between themselves and other parties.
• In about two-thirds of the encounters, at least one group moved to keep a safe distance.
• The university researcher who is spearheading the study said people have been the most compliant on the narrowest and widest paths. Trail users moved off-trail the most on the narrowest paths, said Ingrid Schneider, a professor of forest resources.
