I followed this rule set to make it a little challenging:

- I always shouldn't be able to run (generally you'll always have too much weight, but if I hypothetically do, I should be walking slowly)
- I have to take any item I see not marked steal or is on a reachable corpse of an enemy I kill
- If it is marked steal I should try to take it, but only when there's nobody nearby really
- also have to mine every ore vein, and pick nearby seen ingredients, and take all from nearby containers of course
- you can't get rid of anything unless you're selling it for money

This is the build I used for it:
- Heavy Armour and shield because you can't move for ♥♥♥♥ in combat
- Regeneration magic because you need the health
- Breton class because it gives you 25% magic resist
- "Rush" to the Lord Stone as you need the extra 25% and 50 armor
- whirlwind sprint shout helps tremendously with movement overall
- Horses allow you to fast travel and move a lot quicker in the wilderness
- upgrading health and magic in a 4:1 ratio
- enchanted most of my armor with health bonuses

Now you can probably do this with a conjuration and alteration magic build, but probably not as easily a sneak build.

I beat Alduin with about 6000 carry weight, and will probably still continue from there for quite a while. If you're at all interested at how the run works I streamed most of it as I did it:

This was my first Steam guide, and probably my only one for a while. Hopefully this was interesting to some of you, and gave you some new ideas for ways to play Skyrim.
