An older (30s) guy in one of my college classes saw me watching one of Ryan Hall's Boston races on a school computer one year and struck up a conversation with me. He asked how much I was running that season for cross-country and I replied 80 which wasn't that much compared to what other people run for cross-country. He then asked me, with a dead serious face, what I thought top US elite (relative to the US, trolls...) marathoners ran each week. I replied, most are probably around 100-120 with a few as high as 150. He then nodded and shook his head as if he knew I was going to reply saying that and he said they do 50 tops and there is no reason for me to be doing as much as 80 for cross-country. I ended the conversation quickly and went back to watching the horrible race coverage.. it was better than trying to argue with him.
