This race calendar has been published every year since 2009. There is a lot of uncertainty in the 2021 race calendar. Some events have gone to a virtual format and many events have not published dates yet. Virtual or a V by the location indicates that the event will be virtual and V + indicates that the organizers plan to have a virtual event and an in person event. Nothing is certain in a COVID-19 world. This calendar is updated regularly but be sure to double check for details and changes on the race websites. This Calendar is much easier to view on a computer!
