I can't remember the link, but Mary said she thinks she can run faster. Now I'm not sure how she is strength wise, but I feel like if she were to ever run the 5k sometime soon, that she could do it (sub 15) in perfect conditions. Even Salazar said she was running ahead of what her workouts indicated.
Right now her 1500m "indicates" ~15:10 and an ~8:45 3k.
