fitmiss,
As you know, nutrition is a very important topic and worth of serious consideration for most, if not all endeavours. This is true not only for sporting activities (such as helicopter jumping, skyscraper viewing and floor falling), but for everything. This is because we are what we eat.
I too pondered your question as I continued to lengthen my cycling distance from 1 mile to beyond 10, then 50 then 100 then 500. I said to myself "what do I eat.?" The answer was immediately self-apparent. I decided maintain my daily routine of great, healthy food, a few glasses of wine, no desert and plenty of water. Over the years and way too many century rides, this routine has served me well.
I hope this has been helpful. I have thousands of recipes that I have developed that give me the edge to consistently succeed in my club's cycling events. If you would like to discuss them, please let me know.
