i presume SCSM refers to the stanchart std marathon?
3/4 though today's half marathon, my knees and ankles began to feel
stiffness and pain liao... and its not only the kneecap, but also
the tendon(or ligament) behind the kneecap at the outer edge of our
legs. had to slow down cos of them. had thought be hitting below 2
hrs but couldnt. 
and for that, i really cannot imagine doing 42 km, when the weather
is going to be hotter, and the distance twice!
are the pains normal? btw, before today, the furthest i have run
was 10km - the mizuno and new balance runs. was it cos of lack of
proper preparation that i had the pains? how to alleviate them?
