What do you think was the toughest and most difficult race ever? After reading my September 2011 history column, you might say the New York to Paris. Then there was the 1950-54 La Carrera Panamericana. But these were short-lived point-to-point contests. How about a closed circuit race? In the opinion of many who competed there, it was the Targa Florio. The first was in 1906; the last in 1977.
