Friendship Between Runners

"As we've seen, Aristotle says that developing a friendship based on virtue requires time, familiarity, trust, mutual good will, and mutual sacrifice.  Running provides an excellent setting in which these requirements can be met.  Running with the same person gives you the chance to spend time with them.  Of course, merely spending time with someone doesn't necessarily lead to friendship, much less the type of friendship Aristotle argues is necessary for livinga good life.  But running together, because it involves meeting challenges together, and being with your running partner away from computers, cell phones, and television frees you up to develop a deeper friendship.  Running five miles with someone on a regular basis provides ample opportunity for familiarity, trust, mutual good will, and mutual sacrifice to develop." - Michael W. Austin - from Running & Philosophy: a marathon for the mind

Premise 1 - Friendship is based on many key qualities.
Premise 2 - Running is a good way to exhibit these qualities.
Conclusion - Running is a good way to create and develop friendships.

After running on cross country and track teams for two years I am a firm believer of this conclusion, but does it truly follow from the premises, and have I stated them correctly as they appear in the quote without changing their meanings?

"If the doors of perception were cleansed every thing would appear to man as it is, infinite. For man has closed himself up, till he sees all things through narrow chinks of his cavern."

So you might ask what the name of my blog means, well I took the name from this quote by William Blake.  Now I have a question for all of you, when you read this, what does it mean to you? Personally these two sentences are very important to me and have great value.  But I'm not interested in my thoughts, what are yours?

Fun Fact: Jim Morrison used this quote as inspiration to name his new music group, The Doors.
