Rainsberger debuted tonight at the Stanford invite in the 3k steeple. 10 flat is really solid for her first ever steeple, especially since she ran the whole race alone (only one other competitor who was over 11 minutes). 1:15 final lap and her form looked solid, and didn't look overly tired at the finish. Considering all of the above, I think she could be a major all American contender in this new event.
