What I stated is a matter of opinion. So it may not be correct.
If your asking how I can claim that it takes superior fitness to run the race that Jenny Simpson ran compared with Shannon Rowbery when their times were virtually identical then I will answer like this.
There times were virtually identical and for times sake there performances were virtually identical for that race. However, to use a bad example: It takes a fitter person to run a fartlek for a 4 min mile then it does for someone to race the same time evenly. The person who fartleked the raced didn't perform better, but they are most likely fitter. They likely would beat the other racer if both ran even. Clearly, this is an exaggerrated example and nothing like the situation between Rowbury and Simpson last week, but it's my opinion that Shannon Rowbury does not have the current fitness to have run the same race, using the same tactics, as Jenny Simpson last week.
Does that answer your question or did you have a different problem with my statement?
