It is hard to try and explain the Rythym pattern for 500 Miles, so I found a You Tube Video that explains about playing the chords and the melody.
The instructor is very good and goes over the various ways of playing this song on the Acoustic Guitar.

I hope this is helpful, if not please let me know by hitting reply and I will be happy to try and help you further. Joan
I found a link with some strum patterns: http://banglachords.blogspot.com/2010/10/mr-hall-hundred-miles-anjan-dutta-strum.html
The Key with this song is it is in 4/4 time which makes your strumming more flexible. Joan
I found a You Tube vodeo that teaches strumming patterns that may help. The most important thing I feel is the Chords and the strumming patterns are secondary as they are more fexible. Try and see if this video seems to help: http://www.youtube.com/watch?v=r5MxIANvsA8
