I would say that “He runs fast despite his old age.”
In "Strange Case of Dr. Jekyll and Mr. Hyde", by Robert Louis Stevenson, Utterson and Enfield are taking their usual walk. It is a Sunday. They come to the front of the door in which they have seen Hyde enter and is also the back way to Dr. Jekyll's place. They think of inviting Dr. Jekyll to join them for a walk. They reach the middle window that is half-open and Utterson sees Dr. Jekyll sitting beside the window. When he is addressed Dr. Jekyll answers he is very low, and that this state won't last very long. He says that he is very glad for the invitation but that he dares not to go. He cannot let them in either, because the place is not fit. They plan to talk from where they are. The smile on Dr. Jekyll's face gives place to an expression of terror and despair, as he shuts the window hastily.

Answer: They drew his chariot when Achilles left home for the Trojan War.
Explanation:
The horses, who were immortal, were given by Poseidon as a gift to Achilles's father Peleus upon his wedding to the goddess Thetis: magnificent racing stallions, gifts of the gods to Peleus, shining immortal gifts. Peleus then gave the horses to Achilles to draw his chariot when his son left home for the Trojan War.
