On Jen Rhines, her PR (2006) is 14:55.18. This run tonight (14:58.51) is, to the best of my recollection, the second sub-15:00 5000 of her career.
Hard to say what Jen is, since she won 3 NCAA 5000 championships (I think), but made the olympic team at 10,000 and at marathon. She's got very good range; she'll even put in a few 1500s on the circuit each year. My guess is, though, that she is primarily a 10,000 / marathoner more than anything else.
I watched the stream of the race; Flanagan tried to run up front and paid for it at the end. Never saw Jen or Deena, since they were well back and the coverage was focused only at the very front. Kim Smith (NZ) ran a PR for second.
