But people also think (without evidence) that momentary contact closer than 6 feet is enough to spread COVID. It's almost certainly not.
You are very very very very unlikely to get COVID passing by a person for 2 seconds without wearing a mask. The infected person would have to sneeze directly into your mouth or something.
Just wear it as a chin-strap and it takes 2s to pull up and adjust. Accept that sometimes, your mask will be your only defense, and then hiking is almost as easy as ever before.
This attitude is why the US is still fighting with COVID.
Yes, it's feasible, if people prioritize getting rid of COVID instead of prioritizing beating their speed record.
And I'll probably get downvoted for this just like my other comments because this is the US. If I made these comments in Singapore or Taiwan I'd probably be upvoted a hundred times.
Then, accept that your own mask is good enough. You don't need to wait for the other person. Like sibling comments said, studies show that being outside and briefly walking by someone is not likely to result in transmission, especially when compared to being indoors with others
(b) The problem is we don't know, and I'm in a risk group, so I don't want to take chances until something is proven to be safe.
Also, people seem to think the virus magically stops at an invisible 6 foot distance whereas in reality you need much more if you're breathing and running where you leave a much bigger trail of aerosolized particles as you run, and there's also wind carrying your breath much further than in a still situation.
I do take mask off for hikes when nobody is in sight but I always put it on when I see people are about to pass. What's annoying is people who don't put their mask on to pass you and don't stop and wait for both sides to have mask on before passing. I've been forced multiple times to abruptly stop and backtrack my steps to maintain distance while fiddling my mask on because the other person kept pressing forward impatiently.
