training time increases to 7:15

The time i spend on training slightly increases. During my first week i did altogether 3:15h of training with 1h swimming, 1:30 biking and 0:45 running. The second week (last week) i did 7:15 with spending nearly 2h on each sport.

During all running units i had little aches in my knees. Hence i will very slowly increase my running time.
Swimming is hard as i try to make more than 100km of freestyle and every time i started i only did something below between 50-100m. i don't have any endurance in freestyle. it is such a big difference to running. but last sunday i was so happy to do exactly 200m of freestyle in around six minutes.

My knowledge of my first two weeks of training is not to do so much hard units on running (aching knees) and invest more time in increasing my endurance in freestyle.
[i think one has to invest the time in freestyle and not in breaststroke as you won't have big power in your legs after 3,8km of breaststroke. Even now i feel the difference between both kinds of swimming in my legs.]
