The key thing to this routine or any routine that you choose to use for warming up, stretching and cool down is consistency. A lot of runners will suddenly change their warm-up and stretching routine prior to a big race because they feel they need to be extra prepared or extra loose. However, this could not be further from the truth. As my college coach once said to me, "If you're used to not stretching, then don't stretch." His intent wasn't to encourage me not to stretch, but to stretch consistently. Runners also are so caught up after a race that they forget to cool down, but cool down speeds recovery.
