I was talking about a friend who is getting serious about running and asked me advice since I ran 3 marathons (which is nothing compared to the one marathon per week my friend Scott Dunlap runs, you should read his blog!)
I don’t know about advice but inspiration from those two really great books:
and I followed the Chi Running technique to learn how to not hurt myself. It might sound a little weird but that really helped me a lot.
oh, and I really like the Newton Shoes which are totally flat but still protect you very well for long distance.
