Conclusion

If the nation is going to be kept at home for three months or more, the need for it to exercise,
both for our collective physical and mental health becomes all the more important. The public
should act sensibly, and follow guidance, directions and advice; local authorities should
ensure that sufficient facilities are available for proper recreation to take place, and should
publicise those facilities and locations, and any restrictions that apply to them.

Birds? Not noticed any more than usual really. The Grey Wagtails have just turned up, the longtailed tits are eating me out of nuts and there's a row brewing between some Fly catchers and Blue tits as to who's having the nesting spot in the eves of my workshop. The Dippers couldn't give a toss and are happily doing their thing down by the river.

In a lot of countries walking, biking and jogging are welcome activities in these times of COVID-19. However, it is important to note that you need to avoid each other's slipstream when doing these activities. This comes out of the result of a study by the KU Leuven (Belgium) and TU Eindhoven (Netherlands).

The typical social distancing rule which many countries apply between 1–2 meters seems effective when you are standing still inside or even outside with low wind. But when you go for a walk, run or bike ride you better be more careful. When someone during a run breathes, sneezes or coughs, those particles stay behind in the air. The person running behind you in the so-called slip-stream goes through this cloud of droplets.

The researchers came to this conclusion by simulating the occurrence of saliva particles of persons during movement (walking and running) and this from different positions (next to each other, diagonally behind each other and directly behind each other). Normally this type of modelling is used to improve the performance level of athletes as staying in each other air-stream is very effective. But when looking at COVID-19 the recommendation is to stay out of the slipstream according to the research.

The results of the test are made visible in a number of animations and visuals. The cloud of droplets left behind by a person is clearly visible. “People who sneeze or cough spread droplets with a bigger force, but also people who just breathe will leave particles behind”. The red dots on the image represent the biggest particles. These create the highest chance of contamination but also fall down faster. “But when running through that cloud they still can land on your clothing” according to Professor Bert Blocken.

For running and slow biking it should be 10 meters and for hard biking at least 20 meters.
Also, when passing someone it is advised to already be in different lane at a considerable distance e.g. 20 meters for biking
