To the contrary, if Lorenvolk are equally proportioned to humans, they would be certainly slower if not weaker. There is a reason elephants don't look like giant mice.

Pound for pound, a human is stronger than an individual lorenvolk. Maximum strength figures, however, are in favor for the over-sized human for obvious reasons.

In the case of Robert Wadlow, tallest man ever, cartilage and circulation was at issue. As height increases, distance blood must travel increases twofold, thus Work done by the heart increases by twice the amount height increases.

Robert Wadlow was a member of the human species, and was thus bound by human bio-mechanical limitations. His body, genetically, was not designed to support an unusual height. Lorenvolk, though based on the human species, seem to be specifically tailored to be large.

Breaking news: Biomechanics and physics work the same for tyrannosaurs, elephants, blue whales, humans and fantasy giants attempting to be realistic. By all means the OOC is the place so anyone else considering giants can know the practical ramifications.

As giants, lorenvolk lay claim to greater physical power and greater bone density. An African elephant is a 9 ton creature (actually, when they trip, they have a nastey tendency to shatter bones on a simple impact), while a blue whale cheats physics by utilizing the buoyancy of water.

I thank you for the rapid response. Dialogue is the most fruitful means of conversing :)That the Lorenvolk are stronger given the sort of allometric scaling you are describing is indubitable. A six foot six man, this being for the purpose of determining Lorenvolk weight, has a normal weight of 195 pounds via the Hamwi formula. Double all his dimensions to make him 13 feet tall, his mass is multiplied by 8 as the cube root of length varies with mass proportionally. Therefore it weighs 1560 pounds. Something that huge, as big as the biggest polar bear, should be slow.

It won't be slow. Lorenvolk have longer legs than your baseline human, and therefore can cover more surface area as they run, enabling them to move quicker (and thus move faster) during running sessions. They may be limited by how high of falls they can land from, as lighter creatures are capable of enduring much greater falls than heavier ones (this is why your family cat can drop from two stories and survive, whereas you cannot). For a comparison, brown bears---which can weigh over 1 short ton--can run at speeds of over forty miles per hour, and are frighteningly nimble for something burdened by heavy bones, fat and dense muscle. Granted, they possess four legs (which allows them to distribute their weight more evenly along their length and width), but they still don't dodge physics. It could be argued that such a hefty creature such as the brown bear gets away with its speed and agility by way of its low center of gravity. 

That reminds me: Lorenvolk have an unusually-high center of gravity, and may find it harder to change direction due to their increased weight and said high center of gravity, but they'll still have a maximum speed greater than a human. Expect them to easily keep up with your mounted horsemen with relative ease, with well-conditioned lorenvolk more than capable of competing with your horses in the endurance department.
