i'll spend more time picking up tips about any activity or sport by watching video clips than i will by reading or even receiving directed instruction. something about how my brain is wired craves just to focus (and refocus) on seeing something done well in order to learn how to do it myself.
this is why i have so many marathons on pvr.
reviewing the running strides of the world's best runners seems to imprint on me how to get better at running myself. of course this is a tricky business, since there is no single 'correct' running form, and many different styles seem to excel, from paula radcliffe to masakazu fujiwara to ryan hall to priscah jeptoo ...
anyway, i just came across this article published earlier this fall comparing the form and stride mechanics of the top three men's finishers at the 2013 great north run - kenenisa bekele, haile gebrselassie and mo farah. all great track athletes and now road runners.
if you're interested in breaking down the working bits of the best running strides in the world, this is definitely worth a read!
