Thou shalt not covet thou neighbours PB.
Thou shalt not leave sweat marks on the car seats upholstery. (This one by order from my husband)
Thou shalt not waste money on pedicures.
Thou shalt not add up entry fee running expenses. (This one works on the premise of ignorance is bliss)
Thou shalt not add up running gear expenses. (Ditto above)
Thou shalt not waste weekend mornings sleeping in.
Thou shalt not be a fair weather runner, what are the chances of being struck by lightning anyway.
Thou shalt not remember and enter the next event a few minutes after coming through the finish of a particularly nasty one.
Thou shalt not ever forget that we are so lucky to be able to indulge in this awesome sport we call running.
