If abby improves her time from last year I don't see brenda keeping up but this will definitely be a battle.
I'm surprised by this. Abby D. is a 15:11 gal, even if she improves a good bit, might be in 15:00 shape.
BMart, as you said, went out at 14:45 pace for first mile+ on a windy day at a road 5k and still ran 15:24. I really think that is good for at least 15:10 on the track with more even pacing.
There is also the fact that it was her season opener. That guarantees nothing, but it is common to improve of that, and as such I do feel there is a very legitimate chance BMart could come in here in sub 15 shape.
The other concern for D'Agostino is that she absolutely has to run away from BMart to not get out-kicked, and I really have a hard time seeing this.
