Undergraduate / How Cross Country changed my life (150 words)- activity statement [3]

Here is my 150 word activity statement for the common app. I was hoping someone could critique it to help me improve it.

As I began my run through the early morning frost, I realized that it was my favorite run of the week. To most people on the cross country team attending Saturday morning practice is "optional". It is far too early, includes the longest run of the week, and involves cleaning out the stands. To me though, it is time to clear my mind after a long week of school, and prepare for the weekend ahead. It is also my time to improve as a runner. Before joining cross country I would never have imagined waking up early on a Saturday, let alone running. Those Saturday morning practices showed me that I had to be completely committed to the sport to succeed. I now run up to five miles daily, and my vast improvement has shown me the value of hard work and dedication not only to running, but to life.
