There is a lot of evidence on # of miles being an important component in running. Elite runners can certainly log a lot more miles than less competitive runners.
One number for one person might be over-training, but for another - a healthy number. Just depends on one's running fitness and goals.
As a master runner (63) I only run 3X per week. Next year I am hoping to add a 4th easy day some weeks.
2010 = 231 miles (lots of injuries to overcome this year).
2011 = 839 miles
2012 = will probably reach 860-865 this year.
Next year I hope to increase this by 10%. I would love to log 1000 miles in 2013. It is definitely doable for me.
