New Shoes

Today my new Glycerin came.  My old Glycerin still have a lot of miles on them but I will need new ones before the marathon.  Brooks says that you should replace your shoes after 300 miles.  If I were to run 10 minute miles that is  6 miles an hours.  This means a pair of shoes would last 50 hours of running.  This is only two days and two hours.  That does not seems like a long time for $150 pair of shoes.  If an elite runner runs 6 minute miles they would run 10 miles an hour.  Their shoes would only last 30 hours.  I always replace my running shoes when they get around 300 miles because I don't want injuries but it seems like someone could make shoes that last longer.

Today was a cross training day.  I did stretching and strengthening.
