As I wrote earlier, an urge so strong that you will go out jogging without leaving a change of clothes and a towel for a shower after? She was going to head out to the airport in her dirty, sweaty clothes, remain in them for the entirety of a cross-country plane trip?
No woman I know would ever consider this scenario.
I wasn't aware she had tickets for that day. But FWIW, I once dated an avid runner who ran several miles per day and she never showered after running. She said it was clean sweat. Further, why are you assuming she would work up a sweat on May 1, merely jogging ?
