With rain falling overnight and the race before the final Blue Marble Radical Cup North America race of the weekend using wet weather tires, the option was given to Radical teams and drivers on which tires to use.
After practice and qualifying on Friday, Saturday morning provided the first green flag of the weekend and the first wheel-to-wheel racing for the Blue Marble Radical Cup North American competitors as drivers took to the streets of Toronto.
In the first-ever Blue Marble Radical Cup North America event on the Streets of Toronto, teams and competitors hit the 1.786-mile, 11-turn, barrier-lined circuit for two on-track sessions on Friday.
The Streets of Toronto is one of the premier venues on the NTT IndyCar Series calendar, and this weekend, for the very first time it will also play host to the Blue Marble Radical Cup North America program.
