Sometimes you can start a run and wonder how on earth you are going to make it but you keep going.
Sometimes you are going to walk more than you planned.
Sometimes you have to turn off the stopwatch, because it is going to take as long as it is going to take!
Sometimes you have to suck it up and use the icky, nasty port-o-potty and be very thankful it was there and had toilet paper and soap!
Sometimes a "good job" from a passing runner can motivate you from barely hanging on to run 6 songs to running 9 songs.
Sometimes a High School Musical walk song can put you in a much better mood and ready to tackle the rest of the run.
Sometimes you just keep putting one foot after the other and before you know it you are at mile 7.5 of a 10 mile run.
And sometimes you have to accept a run for what it is, not good, not bad, but rather a building block on the way to 13.1 miles.
