Since she's a runner and endlessly bombards Letsrun message board readers with posts, lets take a crack at profiling her. My initial guesses for starters:
Age: 36
Race: Caucasian
Religion: Possibly Jewish
Marital Status: Single, possibly divorced. Definitely has some feminist man-hating tendencies
Habits and preferences: Fitness, Racing, Health food fads, bad music by middle aged white female singers, Oprah Winfrey book club books, spandex in loud colors
Feel free to add your own take dear reader
