Becky Wade ran a 2:30 at Cal International for the win this weekend. As far as I know, she has been training on her own with no sponsors or training group. She was wearing a singlet from a local running club during the race. She was a solid middle distance/steeple runner at Rice, but she clearly has found her event.
She also spent the last year touring the world and doing a blog about different running hotspots around the world:

Some neat stuff on her blog.
Very strong debut. Look out Desi, Shalane and Kara.
