Slow Motion Running vídeo at @appics seems a good alternative to dtube, specially ...

... because I tried a dozen of times to upload it there without success. This video was taken while I was resting yesterday from a very tough workout, the very same they were doing after me, 6x1000m run at 3’30” , well, the guy of the yellow shirt slightly slower, at 3’50” while the colleague advancing him at 3’40”...note as well the different running styles. Who is more efficient?
