swim pedal run

Soooo if you want to try something that sounds impressive but really isn't hard I suggest a triathlon.  A sprint Tri to be specific.  A short swim a moderate bike ride and a short run.  I am not saying it is easy per se but it is no where near as demanding as a half marathon.  The first two events are very low impact and the last leg is brief enough that you can turn of your brain and just put one foot in front of the other.   In fact by the time you start the run you have such momentum built up that you kind of float in.  And afterward it is just one more thing to say you did.  personally I highly recommend it
