Its the nicely titled ‘Riding with Rilke’ by Ted Bishop. Here’s (what I think is) the opening paragraph:
It wasn’t a mid-life crisis: it was mid-life money. I had inherited some cash and was desperately afraid I would do something sensible with it, like put it on my mortgage or into mutual funds. So I bought a Ducati Monster. I had the fall term off and planned to go to the Harry Ransom Center in Austin, Texas, the improbable location of the best archive in the world of British modernist writers such as James Joyce, Virginia Woolf, George Bernard Shaw, and T.E. Lawrence. Then I got a travel grant from the Ransom Center. They didn’t say how I had to travel. September would be perfect for a ride.
Good eh? As the reveiws say, a book about biking for people with an A level in English Literature.
