Apparently, years and years ago, folks did a walking challenge in honor of the coming premiere of The Return of the King. They now have the walking distances for pretty much every journey in The Lord of the Rings.
I find this very appropriate, because Tolkien (like Lewis and many Oxford men and women) was a great lover of long walks and hikes.
But mostly, it’s just… such a fun plan. 🙂
Hmm. I wonder if you could do this with something like… I don’t know… Xenophon’s Anabasis. Or Jane Austen.

During a lecture on Thomas Hardy’s use of geography, one of my English professors said that when he was younger, he spent a day in “Wessex,” biking through nine Hardy novels. =)
Another great walker is Hillaire Belloc. I love how he dragged his feet behind the wagon when he accepted a lift for the small remaining distance to Rome! =)
I think he also walked over a great deal of America when he was courting his wife, who at the time lived in California.
Xenophon’s Anabasis has been walked, at least in part, by a couple of people. John Prevas, a scholar, and Shane Brennan, an Irish traveller.
I really enjoyed partly walking through Boucher novels when I visited LA and San Francisco. 🙂
I do have to say that I don’t recommend the cognitive dissonance of walking through 1940’s and 1990’s Berkeley at the same time. There are places where you can do that, and sometimes it makes you very unhappy. Because really, from its architecture and situation, Berkeley seems like a place that would make you cheerful and bright and studious; but a lot of the people there are unhappy, tawdry, angry, or convey the idea that criminal activity is about to occur. And that was on a good day at one of our great universities. Sigh.
Oh, and I’ve been to Chincoteague and Assateague. And to some of the places on the Ohio River that Bujold describes in her recent Sharing Knife fantasy series, but that was long before she wrote the books.
