Her Strava is public if you want to look at her training, but I know her and her teammates, I'm from the South Bay. What I mean is that she doesn't train as hard as a typical top high school runner; her workouts aren't geared for what she runs, her normal runs are slow, and she committed to Duke because she cares more about academics than running. I wouldn't necessarily say that she's undertraining, but she's no Brynn Brown and she certainly isn't running anything close to 60mpw.
In the early season, Natalie Cook wasn't nearly as sharp as she was in the end and NP's Sam McDonnell outkicked her at Woodbridge. Both Dalia and Sam were gapped by more than 30 seconds at RunningLane.
