This is why ill prepared runners get short shrift. It has nothing to do with snobbery.
Experienced runners can die yes. But no one wants to advise anyone to run a marathon that hasn't trained well for it.
We all think about the injury potential. Hoever moderate or severe that is the potential is still there.
I stood and watched from mile 17 until the walkers were comming through every few minutes. People who were going to take 8 hrs + to complete the distance. This isn't something that I would recommend anyone do. It isn't something that I would congratulate anyone for doing if they are generally physically and mentally fit. (of course we all know of people who have fought demons, struggled with adversity to get to the start but for the most part we also know that these people trained for it and are well aware of there limitations and competances.)
I will not pat Sally on the back and say well done. She knew she was under prepared. She knew that she was going to have to walk for the best part of 26.2 miles. She knows that if she had trained well that she should be capable of at least the avarage time of 4:15. For many finishing in pain is less demoralising than knowing you havr gone to far and pulling out. It's easier to continue than to give up. Most of us have been there at some point and know this.
Getting a medal for something that you didn't put the effort into seems a little hollow.
Sally knows that now she is fit she can find another marathon, train for it and run it all in a time that anyone would be proud of having put in the training.
It doesn't always work, things go wrong. Run / walking a marathon or any race is fine by me.
