She's faster than he is, no question. Age aside, they're the same height, so he doesn't have much of a reach advantage. But he doesn't need to go far if he's correctly gauged that she's committed her momentum.

He moves to the side as late in the charge as he dares, letting the mace glance off the shield instead of hitting it head-on. He has only a moment before she turns, and he tries to use it to get a blow on her arm as she passes him. It's a testing strike as much as anything; how much is she paying attention to defense?
