Who is she?

This weekend was again one with cycling in the middle.
Today I cycled with Ledig Erf. I kept low profile (stayed at the back of the peleton) and came forward when the hills came up. Then the peleton broke in several parts.
In my group also a girl did her work on head of the pack. But we couldn't keep up with the quickest riders. Though I thought that on the river-dike I saw the front riders. Back in Utrecht it appeared that some of them chose the short distance. For one time I didn't, it must be the girl. She cycled very strongly. We were with 4 men. But when we were back on the track to Utrecht she was the only one who could follow me.
I've seen her before I think, but who is she?
