It has been my experience that learning and then applying the right marathon tips makes the difference between  finishing a marathon or not.
Imagine hitting hitting the wall 20 miles through the race.
You are running along and getting to that stage where every part of your body is saying stop.
Six months of training has taken you that far, six months of dedication has got you through, the crowd has helped, you've done everything right, but it's still not good enough.
That's when it pays to run smarter, not faster.
Having the right tips in how to train and run a marathon really will make the difference between you finishing or not I did for me.
Tips on how to overcome the very real 'wall' can push you through the extra few miles at the end.
Knowing when to push it and when to hold back, when to do deals with your mind and when to refuse, when to listen to pain and stop or when to use that pain and turn it into energy has helped get me around 26.
2 miles time and again.
Professional and amateur runners alike know that you completing a marathon is no easy task.
That said, Comedian Eddie Izzard recently put pay to the in the UK by running 43 marathons back to back, with only Sunday's off.
You can bet your life he had some pretty hot advice and tips to help get him through it.
Another important aspect is having that proper advice to make sure running a marathon doesn't injure you long term.
Training properly and then using the right advice to get you around the course should make completing it all the more meaningful.
Crossing that line after so many miles is just a wonderful feeling, one of the best of your life.
I can't equally compare it to anything.
