While Thanksgiving Day races are the thing in the USA, New Year’s Eve races are traditional in much of the rest of the world. Most are named after St. Sylvester, whose feast day is December 31.
The top domestic race is the Emerald Nuts Midnight Run, a four-miler in New York’s Central Park. The top entries are Bobby Curtis and Desiree Davila. Davila should be considered a “throwback” runner, as she races often and at a wide range of distances but still cranks out great marathon performances.
In Madrid, the distance is 10 km and it is an IAAF Silver Label Road Race.
