Reduce your training during the week of the competition
It is possible to train too much in the final week before a competition and tire yourself out unnecessarily. Instead, see to it that you reduce your training by 40-60% of your normal workload and do all that you can to achieve a pre-race state of relaxation. This does not mean that you should stop running. On the contrary! But you really should avoid long and/or burdensome units during the week of the competition.
