Not sure whether to feel a prat or a bit chuffed with myself but either way, my last weighted run has aggravated an old knee problem and some advice would be appreciated. Currently off to Catterick in a week or so and also doing build-up for the AACC early in 2010 (if I can get a place); so doing loads of phys including Mondays, 7 mile run in trainers (hilly), Wednesday interval sessions on treadmill and Friday/ Saturdays doing a weighted run/ march of either 4, 6 or 8 miles. I have now reached the stage where I am starting to test myself against the course qualifying times and so, on Saturday, looked at the 6 mile speed march requirements on the AACC sheet - (1hour as a formed body). ASSUMED (stupidly) that the weights were for the same as an infantry CFT and weighted my daysack accordingly. Did the run in 1hr 6 mins including stops to pick up my dogs indiscretions and then realised that I SHOULD only have been carrying a max of around 14.5Kg. Needless to say, my knees are a little sore. I've popped the max allowance of Brufen but this doesn't seem to be helping. Any other suggestions guys? edited once for typo.
