She Had no listed time at Half Marathon now 66:53

She paced leading almost every step of the way, which is impressive.
Because she was JUST a pacer, most will not take notice, but I think we may have seen a major star in distance running born, so to speak.
When I read she was going to take the leaders to the Half in 68:00 I looked up her times and thought that she probably would not be able to run that fast, yet, she ran 66:53. New Star.
