15. London Marathon
Every year, more than 40,000 people take part in the London Marathon. Now the race is in jeopardy after the rapid spread of the coronavirus. Scheduled for April 26, concerns are mounting about its viability. In short, officials will make a decision closer to the event.

London might take inspiration from the Tokyo Marathon. Instead of 38,000 taking part, the organizers only allowed 176 elite athletes and 30 wheelchair athletes to compete in the race, which took place on March 1. Let’s hope that it doesn’t come to that and everything calms down.
