The first female on record to walk for pleasure?

The following an excerpt from my new book, Ramble On: A History of Hiking:

One of the first females on record to walk for pleasure and the enjoyment of nature was Elizabeth Carter. Born in 1717, Carter began roaming the coastal lands near her home in Deal, England, as a youth. She would continue this pursuit throughout her entire life, in an age when women didn’t walk alone. During her lifetime, it's believed she walked thousands of miles, mostly alone, but occasionally with her sister or a friend. Many of those walks and extended rambles were documented in correspondences she exchanged with friends. Carter gained national fame as a writer and poet, and would eventually become associated with a literary, educational and social movement known as the Bluestocking Circle.
