Marathon training. Trying to do it right. Yesterday I was supposed to run 16 but I accidentally got a little lost and ran 16.87. Those 0.87 hurt! Dang!
You'd think that the main reason for wearing a GPS device would be to prevent someone from getting lost. In my case it only provided a bell at each mile and a frequent unpleasant tone from mile 12 on, admonishing me to "SPEED UP!"
It was a little bit demoralizing but at least I got the miles done.
