I run with a rucksack quite a lot, and it's pretty miserable with a heavy bag. My normal small bag is fine but a few weeks ago I had a long wait between trains so went for a run with a 15kg bag and it swung about a lot and my legs felt glued to the ground. And I got a friction burn on my collarbone.
