A post-operative transsexual, Michelle Dumaresq has provoked outrage by entering the sport of women’s mountain bike racing. This program studies complex issues of gender identity surrounding the controversy and manifested in Dumaresq’s personal and professional relationships. Commentary from her parents reveals unconditional support for her choices, while interviews with friends and rival cyclists indicate a wider range of positions—from confused ambivalence to a belief that Dumaresq is male and should be barred from competing. A candid look at clashing views of femininity, 100 Percent Woman explores challenging terrain in gender sociology. (60 minutes)
