The 2023 The Loop 121 was the 16th stock car race of the 2023 NASCAR Xfinity Series, and the inaugural iteration of the event.

The track for the actual race in 2023 ended up being the exact same layout as the version used in 2021 for the eNASCAR iRacing Pro Invitational Series.

The start/finish line is located on South Columbus Drive in front of Buckingham Fountain in Grant Park.

The cars will then turn right onto East Roosevelt Road and then make another right, which gets them back onto South Columbus Drive where they are going north.

When they are back on East Balbo Drive, they will cross a bridge over the Metra Electric District tracks.
