Sorry if this has been done already, but can't find it if it has. I'm recovering from some quite nasty ankle injuries and am at the stage where I can start building strength back up. I was planning to go out on a 4 mile CFT some time in the week with a reduced load of about 15kg just to see how the ankles held out. Question 1 - After a time of about 4 months of not being able to do any running, let alone with weight, is 15kg too much? It'd just feel a bit useless walking around with a bergan seemingly filled with air. Question 2 - Beforehand I've done CFT practice with just an old backpack of mine. Problems being 1) it rides uncomfortably on my back and 2) It's a bastard if I want to carry easily accessible water. Would I get beaten to death by a MATTS pamflet if I do CFTs locally with webbing/bergan? Is this considered a breach of persec? It's just without spending £60 odd on a new decent civvy hiking backpack I'm a bit stumped.
