"When you are moving — running, cycling, walking — you are actually creating an area behind you that is often called a slipstream," study coordinator Bert Blocken told the Brussels Times, explaining that athletes often use such "slipstreams" to boost their speeds.
Blocken also told The Globe and Mail that anyone seeking an outdoor workout during the coronavirus pandemic should maintain a distance of at least 15 feet from the nearest person when walking, 33 feet when running or cycling slowly to moderately and 65 feet when running or cycling vigorously.
Critics cautioned on making too much of Blocken's research, which is preliminary and has not been subject to the peer-review process, according to Vice.
