And, on the first Saturday in May, that's exactly what they do; women's motorcycle clubs and riding groups in more than 20 countries get out there on the roads to highlight the growing number of female riders worldwide, encourage women who've always wanted to ride but never had the gumption to get their butt on a bike, and make their presence felt "in numbers too big too ignore". International Female Ride Day was founded in Toronto, Canada in 2007 by motorcycle racer, riding instructor and founder of online women's motorcycle magazine Motoress, Vicki Gray.
