How fast should a young lady be at 5k/10k before making the decision to turn pro.
Assumptions:
Age: mid/late teens (16-18)
Looks: Attractive all-american type
Personality: bubbly, humble
Potential: good background, good leg speed and outlook for improvement is great.
(all important for endorsement potential)
I say sub 15:30 and sub 33:00
Slower than that and a scholarship to a major division 1 school would be worth more than pay as a professional money.
