The Times reported today that Paula is planning to run the WXCh (though is not 100% confirmed). Apparently she might use it as part of her preparation for the London Marathon:

She updated the diary on her site today, but there's no mention of the WXCh. She did mention, however, that she's moved back to Albuquerque to train because Flagstaff was too snowy and rainy.

There's a cool pic of her doing an indoor track session.
