Focus on Posture At Start of Run

From Owen Anderson

(Editor's Note: It's a long article with a lot of obvious observations and some debatable recommendations. That said, still worth the read to challenge your viewpoint. Below is one worthwhile reminder.)

Perhaps the only consistent difference in running form during the bike-run transition (compared with regular running) is that athletes tend to run with a more 'stooped' posture - ie with their upper bodies inclined forwards(13). This 'death-march' style may be a sign of delayed adjustment from the forward-leaning style of cycling; alternatively it could reflect fatigue. However you explain it, the forward slump probably produces a dip in economy and may be responsible, at least in part, for the 1-12% drop in running efficiency commonly observed during the bike-run transition.
