Sleep
Athletes, because of the nature of what they do need more sleep than most people.
Poor sleep (under 6 hours a night) is a common result of athletes trying to cram all
their training into their lives, whilst not missing anything else that everyone else does.
It leads to a deterioration of all aspects a persons life, which is often noticable first
in a drop off performance levels.
This is both a physical and mental deterioration with loses in cardiovascular performance
and also a tendancy to lose motivation.
Diet
Nutrition is what keeps us alive (with a bit of breathing!). If your diet is very poor
you will not be able to perform optimally. Sports nutrition
is discussed in other areas of the site, but here just be aware that you will need
to look after your diet to be able to train and recover well.
Support
Support from family and friends is very important. You will be putting a large amount
of time into your sport and will need, at the least, understanding of what you are doing
from your family and friends. This will often be helped significantly by having friends
who are helping you with your running, whether it be other athletes, a coach, a mentor or
even just a person who acts as a sounding board.
Believing
Take ownership and responsibility for what you are doing. It is your life and your
running career. You need to take control of what happens in terms of all aspects of your
sport, even if that involves the conscious decision to delegate aspects of it to others - eg
a coach, masseur, nutritionalist etc. This is very important for motivation and essentially,
if you believe in what you are doing then it will make you run a lot faster than if you are
told to do something you don't believe is right - even if it is!
