mid-stride crisis

In recreational running, the propensity for any man over the age of 40, when passed by a female, to immediately speed up to reclaim the lead. It is not uncommon for men prone to this affliction to stuff their running shorts with rolled socks.

I was out on the running trail when I passed this old man wearing really short shorts. He had a mid-stride crisis and immediately doubled his pace to keep up with me; his belabored breathing and flushed skin had me concerned that a cardiac arrest was imminent.
