Nina Dobrev Takes Part in Tough Mudders Race wth Miriam McDonald

Nina Dobrev took part in another tough mudders race today, September 11 in Toronto. Nina was joined at the event by her friends including Degrassi costar Miriam McDonald.

Nina has been in Toronto for the past couple of weeks filming her new film, Flatliners. Last week filming on the film began to wrap and Nina and her costars began to say goodbye to one another.

Nina must love doing these things. Has anyone ever done a tough mudders race? Are they fun?
