You know, speaking of men and women, this is exactly the kind of thing a man wouldn't think twice about. Running marathons on no training at all. How many times have you heard that ... and how many times has it been a woman? I met a kid the last time I did TOSRV who said he'd ridden 35 miles that year. Total mileage.

You can do it. You may be sore afterward... but if you want to, you can do it.
