It makes some logical sense, however it doesn't take into account wind direction and intensity.

The article states "On the basis of these results the scientist advises that for walking the distance of people moving in the same direction in 1 line should be at least 4–5 meter, for running and slow biking it should be 10 meters and for hard biking at least 20 meters". "When you are positioned diagonally behind each other the risk is also smaller to catch the droplets of the lead runner. The risk of contamination is the biggest when people are just behind each other, in each other’s slipstream". This however assumes the wind is light and/or the lead runner has a head wind. What if there is a cross wind? What if the runners have a tail wind?

The article and perhaps the study is incomplete or flawed. The article clearly states the study and animation is usually used to measure and improve the performance of athletes. "Normally this type of modelling is used to improve the performance level of athletes as staying in each other air-stream is very effective". For this to be effective, the runners intentionally run very close to one another where wind strength and direction have less of an impact.
