In Photos: 2017 Grand Prix de Trois-Rivières

This summer marks 50 years since the first time the streets of Trois-Rivières were turned into an urban circuit – a tradition that's run every year since, except in 1986 and 1987. Thus, it's the 48th weekend of tri-fluvial competition that's just wrapped up, with 13 events that ran the gamut, and a field of drivers who ran against each other – and sometimes the retaining walls.

In the running: strange IMSA prototypes, roaring Canadian NASCAR entries, legendary Porsche GT3s, and tiny Nissan Micras – driven by such characters as humorist Michel Barrette and comedian Jeff Boudreault.

As for the rest? Check out the pictures above.
