I'd be lucky to consume 2,000 calories in a day, which leads me to believe I'm not eating enough to sustain myself during my long runs. Take a look at the American Heart Association Calorie chart below.

I usually run about a 5.5mph during my long runs so I would burn about 570 calories per hour for my weight. Last Sat, I ran approximately 15 miles, skipped breakfast, had a banana and later a bowl of pho for lunch. Ran some errands and had a salad, bowl of rice, and a handful of carrots before attending a wine and cheese fundraiser. I ate a lot of cheese and crackers that night so I'm guessing my total calorie intake for that day hovered around 2200. Wine has calories too so I might be a little off in my guesttimate. But I pissed most of it out so maybe not.
What does this all mean? I should probably eat more as I'm looking a bit thin in photos these days..
