4-7 days post marathon you are probably in the best state to objectively review how you did as it will still be reasonably fresh in your mind however you will be getting back to a sense of normality and the aches and pains will be receding.
So have a think about what you did and ask yourself some key questions?
- Did you achieve what you wanted to achieve?
- Review your preparation. Was it ideal? Is there anything that you would change or do differently?
- Review the day itself? How did you feel both physically and mentally before, during and after the marathon?
