The many 100 mile race reports which can be found on the internet is a blessing, and I am grateful to all of the people who take the time to write and share them. Some people like to socialize as they run, others listen to music, some wear their watches and habitually look at their wrists to see if they are hitting their goal pace. Runners with backpacks filled with enough supplies to last a week in the wilderness contrasted with the minimalist gurus who run barefoot and don't carry anything except a water bottle. The runner who carries a camera and stops to make pictures every 2 miles. The ones who eat fancy sounding, processed "energy" foods (Perpetuem, Boost, Ensure, Vespa), and more often than not their blogs are advertising said products.
What I have discovered is that there is no miracle food, no magic shoes, no fool proof method to prevent blisters or upset stomach (although some who write lovingly about drinking Ensure or Boost at mile 15 later in the report write of vomiting and shitting uncontrollably at mile 30, which makes it appear that these products have joined Olestra in the "pay lots of money for a product which makes your stomach hurt and bowels explode, and do it with a smile on your face" category). Each runner has to cut their own path through the wilderness of misinformation, propaganda, and devious marketing.
