David A. Lally, Ph.D., an exercise physiologist at the University of Hawaii-Manoa completed a careful study of 1543 individuals who participated in the Honolulu Marathon, and his investigations actually link pre-workout stretching with a higher risk of injury.
In Lally's survey, 47 per cent of all male runners who stretched regularly were injured during a one-year period, while only 33 per cent of male runners who didn't stretch were hurt, a statistically significant difference
Lally's analysis did yield one fascinating bit of information. Those marathoners who stretched before training sessions had higher rates of injuries, compared to runners who didn't stretch. However, athletes who stretched after their workouts actually had lower frequencies of injuries.
Make of that what you will, I personally never stretch pre-workout and even if doing an event warming up is a brisk walk at most. I only stretch after running
