I use Hammer Nutrition products exclusively and they use no simple sugars in their products but are really opposed to HFCS. The July 2010 edition of their magazine, Endurance News, had a great article about a March 2010 study done by Princeton University. Three groups of rats were given different diets. Group A got rat chow and water, Group B got rat chow and HFCS water (at 1/2 the concentration of soft drinks) and Group C got a high-fat diet. The result was a increase in weight by some of the rats on the high-fat diet but all the rats on the HFCS water became obese. They found that the HFCS is processed by the liver into fat while sugar went into the bloodstream to provide a glucose/energy boost (though temporary).

Here are 2 great books I received as gifts: 17 Hours to Glory by Muller/Carlson and Trizophrenia: Inside the Minds of a Triathlete by Jef Mallet. Jef is the cartoonist/triathlete who created Frazz, the songwriter/school janitor/triathlete cartoon character. Jef's book has some hilarious observations on triathletes and makes us laugh at ourselves. ("How old is your new girlfriend? She's 30-34 age group.")
17 Hours to Glory profiles 17 Pro or Famous triathletes in their quests at the Hawaiian Ironman. It really give you an insight into the training levels of Iron-distance athletes. Both are available at Amazon.
