Varsha was permitted by Fox to host three F1 races during the 2013 season for the NBC Sports Network (the three races that are on the same day as an IZOD IndyCar Series race—Malaysia, Belgium, and Korea—as regular lead host Leigh Diffey was also lead host on IndyCar broadcasts for NBCSN), which carried F1 in the United States until the end of 2017. In 2014, Varsha was again permitted to work with NBCSN's coverage, but NBCSN decided instead to have Varsha be lead broadcaster for the Verizon IndyCar Series races instead of Formula 1, where Diffey remained lead broadcaster for the entire season. In 2014, Varsha worked Carb Day, Pocono, and the Toronto IndyCar race weekends.
