The Loop 110 is a NASCAR Xfinity Series race that is held on the Chicago Street Course, a street circuit in Chicago, Illinois. The race was first held in 2023 and was the first ever street race for the Xfinity Series. A NASCAR Cup Series race is also held on the street course on the same weekend the day after the Xfinity Series race.[2]
On September 14, 2022, NASCAR announced that the Xfinity Series would have a race there when the series' schedule for 2023 was revealed.[3] The Xfinity Series race at the Chicago Street Course replaced a planned IMSA race that was going to be held on the same weekend as the Cup Series' race there.[2]
On March 7, 2023, NASCAR announced that the race would not have a title sponsor and would instead be named after the Chicago Loop, the area of the city in which the street course is located. Similarly, the Cup Series race was named the Grant Park 220 as the street course passes by Grant Park. It was also announced on that day that the Xfinity Series Chicago street race would be 121 miles and 55 laps in length.[1]
The 2023 race, which was won by Cole Custer, ended up being one of few races in NASCAR history that did not go past halfway in its scheduled distance. The race had to be stopped after 25 laps on Saturday, July 1 due to rain. With the race not being halfway finished, it was scheduled to be continued on Sunday morning. When it rained again on Sunday morning and then the Cup Series race had to start on time and how the street course had to begin being dismantled on Monday, NASCAR decided to call the Xfinity Series race. It also was one of very few races in NASCAR national series history in which one driver led all the laps in the race.[4]
On October 20, 2023, NASCAR announced that the 2024 Xfinity Series Chicago Street Race would be shortened from 121 miles (194.731 km) and 55 laps to 110 miles (177.028 km) and 50 laps.[5]
