Taxman thanks for the post. By the way, I'm an AF ALO (Forward Air Controller). Was enlisted for 9 years as a SF TACP. I've seen my fair share of ruck marches, the last one I did was in Afghanistan the middle of winter, snow, mountains, and a 120lb. ruck for 12 miles. And the worst of it all, doing it under 4 hours. But, you're right I didn't have a platoon of Marines yelling at me not to run.
