The 2021 Superkarts! USA Pro Tour resumes this weekend with the 11th running of the SpringNationals. Competitors will converge on the Utah Motorsports Campus to continue this year’s SKUSA Pro Tour championship program, which began back in March at the NOLA Motorsports facility for the WinterNationals. The May 21-23 event in Grantsville, Utah will host Rounds Three and Four as the 12th season for the longest running national series program continues.

The inaugural SKUSA Pro Tour event was back in 2010 with the first SpringNationals at the Sonoma Raceway facility. The SpringNats was the opening event to the SKUSA Pro Tour until 2017 with the introduction of the WinterNationals. With last year’s program held all at the New Castle Motorsports Park for the Summer Festival, this marks the 11th running of the SpringNationals. The Utah Motorsports Campus opened in 2006, known then as the Miller Motorsports Park. SKUSA has visited twice before, once in 2012 for the SummerNationals and lastly in 2019 for the SpringNationals. The Star Trek layout at 9/10-mile with 18 turns in the clockwise direction is the circuit for the weekend, with temps set to be at the mid 60s all weekend. Read full story on eKartingNews.com
