In these conditions of COVID-19, cycling is encouraged in many nations.
It is important to remember, though, that when you do these things; you have to stop dropping each other. The study of KU Leuven in Belgium and TU Eindhoven, in the Netherlands, is the result of this research.

The students reached this conclusion by simulating the phenomenon, from various locations (both diagonally behind one another and immediately behind one another, of saliva particles of the citizens during motion cycling, walking and running.
In a variety of animations and graphics, the test effects are clear. There is an easily visible droplet cloud left by a human. “People of stronger intensity who sneeze or cough outlets, but even people who breathe, will leave contaminants behind. ” The picture’s red dots represent the most important particles. This generates the greatest risk of pollution but is still minimized more rapidly. According to Professor Bert Blocken, “Especially when they go through the cloud, they still can fall on your clothing.”

From the simulations, the role of social distance in cycling next to each other seems to be less for two persons in low winds. Behind the couple, the droplets settle. The chance is lower to capture the droplets of a lead runner if you stand diagonally behind each other. When people are behind each other in the slipstream during cycling , the risk of contamination is the greatest.
Based on this observation, the scientist recommends that it should not take 4-5 meters to shift the distance of those who are cycling in the same direction on one side, 10 meters to cycle and slow and at least 20 meters to cycle quickly. It is recommended if you are still at a reasonable distance, e.g., 20 meters for cycling in a particular lane while passing others.
This is certainly something I would think and also brings the closure of busy parks, etc. into context. Maybe the safest option is to only go cycling during covid-19 on the road, alone, or at least with enough space. Keep safe … Stay safe …
