A llama won't outwalk you. Their favorite gait is what we call a slow ramble...except coming back to camp. Some of them will push you when camp's getting close. I carry a trekking pole to whack a front leg on occasion when one gets pushing too hard. That usually slows them down.
They're much easier to handle than horses because you don't have to carry feed unless there's a fair amount of snow and they normally won't get tangled up in tether ropes. I just lay a long line on the ground with o-rings laced into it and tie them to the rings. If they get their feet tangled up, they'll just keep working their feet until they're untangled.
However, there are times when riding would sure be nice.
