Great to hear about your race today!
7.17 for the first mile! Your coach will be happy with that I bet- sounds like you did exactly what you were supposed to do- let us know about the debriefing!
Emily- Wahine will probably jump in here but my understanding was that her race tactics were aimed at a bigger overall plan of breaking some preconceived "barriers" not necessarily to race that specific 10km with the goal of doing a personal best in the most efficient tactical way.
Though if I ran 10km at that pace it would be a PB-I would love to run 10km in 50min!
Good job again Wahine
