Runners, please continue to mask up!

Some updated perspective for athletes as we start to move outdoors again—what do we know now that we didn’t know last summer and fall, and how far apart do we need to be? This is important for people who may come in contact with runners and bikers as they venture outdoors as well.

First headline: it’s now well established that COVID is transmitted via aerosol transmission. This article explains how that works in detail, and transmission is not limited to large droplets in close proximity, but also occurs iva aerosols at much larger distances.

Second headline: six feet is not near enough, especially when considering well-established slip-stream airflow dynamics for runners and bikers. You should never run or bike or walk directly behind someone else, and even with offset the distances you need to leave are 15-20 feet for runners, 30 feet for slow bikers, and 60 feet for fast bikers. That’s if you’re moving in the same direction; if you’re coming at each other, best to step off the path completely. Updated article about aerodynamics:

Third headline: just because you’re vaccinated doesn’t mean you can’t contract or spread the virus. Vaccines do not give you sterilizing immunity, only some measure of effective immunity which is also impacted by the vaccine rates of the people around you. Even after completion of a vaccine protocol, you can still be part of a chain of disease, spreading virus even if you are asymptomatic. It remains critical to continue to wear masks in public–this especially means us, runners and bikers. Helpful information:

Please continue the efforts to keep everyone safe. There is no one single solution or safety method–we all need to do everything we can, every single time, to slow or prevent the spread of the virus.
