A schedule for Watkins Glen International and the Streets of Nashville, August 2021. The NASCAR Series are back after two weeks break at the Glen. There will be NO practice or qualifying, lineups are set by the NASCAR-metrics for all three series. IndyCar is back after the Summer break however the Indy Lights guys have one more week off. First time for racing First time for IndyCar to take on the Streets of Nashville for the first time. Details here. From what I can see this is going to be an interesting race weekend after a couple of weeks without Racing.
