I am considering an interservice transfer to the PJ/CCT community. I have had surgery on both my feet for plantar facitis. I am back to running 20 miles a week and I shouldn't have a problem with the PAST, but I am concerned about the humping I will have to do in the pipeline. What is the maximum distance and weight most people hump with?

The rucks start at about 40lbs and 6 miles. They finish at 15 miles and 60lbs for time. Remember, as a CCT, you are the HEAVIEST man. You will have a radio, batteries, possibly runway/DZ lights or a laser range finder and a bunch of other stuff in your ruck. 100lb rucks are common and I've never been to the field with a ruck less than 60lbs, and that was only because the guys I was supporting were light and distributed MY gear among them. This was an unusually supportive team who LOVED CCT and volunteered to do so, which is NOT typical.
If you have any worries remember the fact that not only are you the heaviest guy out there, you may be asked to leave your team and go in with a bunch of guys you've never met. You will be expected to learn their IADs and SOP, hand signals ("I only know the Air Force signals!" only works in Saving Sillverman) They are not going to slow down for you and most likely will have no sympathy if you can't hang. Remember, most SEAL and SF Teams really dig parts of the CCT mission and would like to do it themselves. YOU can not afford to fall behind and give them a reason NOT to use CCT.

I'll agree with GaurdMc on this. You are going to be carrying the most weight and your not going to have a choice 90% of the time. If your just worried about making it through training, then maybe you should rethink your career choice. You should be thinking past that and how your injuries will affect you after training. Running is good, but if you can't carry you gear and keep up, your useless.

However, if you've fully recovered from plantar facciitis and are now running 20 miles/week, you can build up your feet to withstand the pounding of long ruck marches. Therefore I see your question as legitimate. If you start now with, say, 20 pounds in a backpack for a mile or two and eventually you are going 6 miles with 65 pounds at 15 min/mile without any effort or discomfort at all, then I'd say you can handle the pipeline. Thats pretty much the way it worked for me; Early on in my career I experienced bilateral stress fractures in my metatarsals after rucking the equivalent of a couple hundred miles over a couple weeks. I built back up slowly and have humped the lovely 100 lb ruck without porblem on several occassions since. The key for me was gradually increasing weight and distance without overdoing it.
At the same time, thses guys are giving you a pretty clear picture of the scrutiny that may befall you. The operators world can be ruthless and unforgiving.
