(CNN)After the pandemic scuppered last year's New York City Marathon, one of the world's most prestigious and hotly anticipated running events is set to return on Sunday.
Last year's race was meant to mark an extra special milestone -- it would have been the 50th running of the iconic competition.
But like so many aspects of regular life, the world's largest marathon fell victim to the pandemic in 2020 and was canceled due to health and safety concerns.
What about Covid-19?
This year, runners will face some restrictions to mitigate the risk of Covid-19, including social distancing, elimination of touchpoints, enhanced health and safety protocols and testing and tracing.
Participants will need to provide proof of at least one round of Covid-19 vaccination or a negative Covid-19 test from within 48 hours of race day, and face coverings will be required on public transportation during race day, at the start, at the post-finish area and at the Expo.
Where will runners go?
Some 33,000 people will attempt the grueling 26.2 miles through the city's five boroughs.
The race starts in Staten Island, where runners will advance north to Brooklyn, Queens, before taking the Queensboro Bridge to Manhattan. Athletes will run down Fifth Avenue before finishing in Central Park.
