The Kona Rating Report is the best resource to look forward to the Ironman World Championships and to follow the race! It's a 120+-page PDF with information about the race, all Professional participants and their chances on October 14th.

The report is available for free (just enter 0 in the "Name a fair prize" field you get after clicking "I want this"). However, if you like the report and want to support my work over the year, it would be great if you can send me a few bucks. (For comparison, triathlon magazines sell for about $7.)
