The day of questioning

So as days of training start to go by , you question your sanity. You question what you want to do, what you want to achieve out of 1 race. After a couple of hard days in a training week , your body starts to feel the wear and tear. You feel mentally burnt from work and the workouts, you feel physically tired, your muscles feel fatigued even after a rest, you search your inner self to find out if you have it in you to do the next workout. Is that what it takes ??

A lot of triathletes talk about paying your dues. Is this what I own to the gods IM.
