Marathons aren't for everyone. There are folks who stroke
out in the middle of a marathon. Not to mention ligament
injuries and all.
The night before, whilst doing stretching exercies, I heard a
muted squishy sound. It was very soft and I could hear it
only cause it was the middle of the night. I realised the
sound only came when I do my stretches and I slowly traced the
sound to... my right knee! 
I've gone to the doc before to tell him of my chronic persistent
knee pain but after a check, he just said that my ligaments holding
the knee cap in place might have gone a bit off-center... because
of age. Someone like me, if I even attempt
pre-marathon training, will probably pop the knee cap and render
myself handicapped!
I know.... after three marathons, I still can't run 42 km
non-stop.
I had to go into run/walk mode after 35km of continuous
running.... my muscles just couldn't handle all that continuous
pounding.
At least I've been showing improvement.... in the first
marathon, I started walking after 25km.
Also, my recovery period has gone down.... in the first
marathon, it took me two full weeks to recover from it. By my third
marathon, though, I was back to normal after three or four
days.
