In case I was getting too comfortable with my running, today was a wakeup call. I had my first 5 mile run. With the way 4 miles had been feeling lately I figured it would not be too hard on me. I did not count on having to run against a 10 mph headwind most of the way.
At first the wind felt like a nice breeze that would keep me cool. By the third mile my pace started to slacken. Early in the fourth mile I began to feel how much my strength was being drained because of that extra resistance. I was walking into that wind for quite a while. Based on my time and my energy level at the end of the run it felt like a 6 mile workout rather than 5.
