Here is some advice from the article Coronavirus & Cycling: Your Best Protection Tips, with additional info from other sources including medical professionals in the WW club. This is a rapidly evolving situation, so the advice might change between the writing and publishing of this article.

• Don’t ride with others if you are not 100% healthy, even if you think it is only allergies. We all have a responsibility to reduce the spread of this illness.

• Keep groups small or ride solo. Remember people can have the virus and not show symptoms.

• Religiously practice social distancing, keeping at least 6 feet away - much more when behind another cyclist. To visualize this, imagine you and the other person sticking your arms out toward each other - if you can touch fingers, you are way too close. 

• Bring antibacterial hand cleaner on every ride. Use the hand cleaner or wash your hands before, during, and after the ride, and at every restroom stop. Thoroughly wash your hands the moment you get home.

• Minimize hand and finger contact with your eyes, nose, ears, and mouth. Become hyper aware of when you touch your face and do not do it!

• Refrain from spitting or blowing your nose into the open air. This can easily transmit the virus (Bicycling article link).

• Do not draft! When you ride behind someone, increase the distance to 2 to 3 seconds behind (count one-one-thousand, two-one-thousand), to avoid breathing their freshly exhaled air or droplets.

• Slow down and ride defensively. This is not a time to have a trip to the ER and there might not be a hospital bed available for you.
