Running a marathon isn’t a stroll round the park; a marathon is not even a long run. A marathon is 26.2 miles of continual effort that will sap your body of energy and leave you exhausted at the finish line.
A marathon is also an exhilarating experience, something that you can share with thousands of people. There aren’t many sports in which you can toe the line with olympic champions and world record holders: marathon running isn’t exclusive. When you stand on the starting line, you could be doing so alongside world record holders.
However, at the end of the day, regardless of how many people there are around you, the only person that can run the marathon is you. You are responsible for getting round the course and you are responsible for making sure that you’ve taken the right measures to do so.
