Why aren't you killing them instead? Heh.

As mentioned by knighttemplar, the only mobs you can't outrun are the mozzies and wolves. This sounds like a stamina problem.

Stamina management is absolutely a thing in this game. You need to balance your foods and make a stamina potion for an extra boost where necessary.

Kill the first boss and the power they give you is a stamina boost which makes it easy to get away from everything and you can cover long distances on a full stamina bar.

Preserve stamina by shouldering anything you're carrying too.

Hope that helps!
