Last (and actually the only) time I ran the full 13.1 was way back in the spring, on the flats. I've only made it to 12 in the hills (with about 1200 feet of climbing). But the race will be flat and I'm not expecting any trouble with the distance. Not sure what kind of pace I'll be able to maintain though... speed work has taken a serious hit over the summer, between training for the cycling event, and the recent travel.
This weekend I'm at a fitness convention and don't anticipate any running on top of all the indoor workouts/workshops. Ugh. Maybe get a run in before my flight Monday.... maybe, if I'm not too whipped.
In more interesting news, I FINALLY talked to one of the presenters here who is both a big advocate of barefooting/Vibram Five Fingers, and knows exactly the problems I have as a result of Morton's Foot and agrees that it's a true pathology and not a flexibility issue. He thought it would be perfectly appropriate and workable for me to pad my first metatarsals inside VFFs.
I haven't yet found the ideal material and height to pad them inside regular shoes - still working on different solutions - and I'm sure not going to try barefoot running before the half marathon. But I'm looking forward to trying it soon!
