Except a case for hr jogging there can be easily made.
She had just terminated her membership at health club which ended at the end of the month or Arpil 30, People used to working out regularly or daily are like addicts they need to keep something going everday.
On May 1, the first day w/o a membership she could have looked up local jogging paths on her computer and then left to go jog the trail.
A local jogging path, eight miles away, in a secluded area, without her cell phone? With her bags packed to go home, she suddenly got the irresistible urge to jog on a path she'd never been to before (had to look up the location on Map Quest). If that's the case, maybe she was suicidal.
Personally, for nearly 10 years I rarely go more than 2 days without jogging. The exceptions are always outside of my control, such as being in Russia in winter, sickness, extended rainy weather. (I'm not that much of an addict.) I do run in snow, early in morning or indoors during hot weather, and parks in the spring are among my favorite places to go.
Her bags all packed up, the last thing she's going to do before taking off for home is go jogging?? No way, IMO -- you get yourself all sweatied up, no change of clothes, no towel for a shower after, but you're ready to catch a cab out to the airport in your dirty, sweaty jogging attire ... that don't add up. My sister wears workout clothes on cross-country plane trips, they're more comfortable for her. But she doesn't run or workout in them before she gets on the plane. Chandra Levy was NOT out jogging in that park that fateful last day.
