Stay motivated with us this fall with our free running challenge! The Runstreet X Clif Bar Canada Wolf Pack Fitness Challenge kicks off Oct. 1 and lasts 30 days.

I have been following kick ass Canadian runner Roxanne Gail on Instagram for some time now, and if anyone epitomizes superwoman, it is her. Roxanne slays ultra marathons, trains through dirt, mud, rain, cold, heat and I'm sure would continue through an apocalypse as well.
