Ratio of run/walkers to pure runners

I have intentionally run/walked from the beginning and don't really forsee changing that but you never know.  My first half marathon I did run 10 minutes, walk one.  For my most recent one I was injured so it was run 5, walk 1.  If I plan my walk breaks, I don't end up having to walk the last 2 or 3 miles b/c I ran out of gas.

Great information!  Thank you all!  I will do my first 5k on the 23 or 24th of this month.  It is a fun run/walk.  I'll be walk/running.  This time anyway.
