The Athens Marathon - and the postponed Athens Half Marathon - have been cleared to take place later this year, with social distancing restrictions.
The Marathon is set to be run on November 8, with the Half Marathon - postponed last March - currently scheduled for some 50 days earlier, on September 20.
Greece has so far succeeded in holding COVID-19 relatively well at bay, and authorities have approved a health protocol putting a ceiling of 5,000 participants on individual road races.
For this reason, the 2020 Marathon will be split into two individual races of 5,000 runners each, with the second race starting an hour after the first.
Allowing for four shorter races taking place over the November 7/8 weekend, organisers expect to cater for a maximum 30,000 competitors over the two days.
