.... or look at it another way... you are running longer. Time on feet counts. the longer you run, the longer you can run. So you're actually doing yourself a favour.

i do that in all my races too. I run slowly so i get the most value for my dollar. The longer I'm on the course the better value I get. not like those people who pay the same amount as me but only get to race for a measly 5 hours or so. I get to race for waaaaay longer than that hehehee
