So today my morning cycle started with a rucksac weight of 11.1kg, I weigh 79.2kg, that's almost 15% more, high-up on my back - the wrong place for stability.
How heavy, is too heavy, when it's a rucksac....?
And, for the physics/maths gurus'... is there any science that could help with a definitive answer?
