Basic Technique - Law Running and Air Running

Tip: Travel as light as possible while running runes! Don't bring any armor that weighs anything!
Perquisites:
- This technique is for both non-members (Air Running only) and members
- Any level
- Any amount of gold
- 25 Rune Essence (Air Running) to 27 Pure Essence (Law Running)
- Air Tiara (Air Running) or Law Tiara (Law Running)
There is little or no risk in Rune Running. This can be done by any level player with any amount of cash.
Law running and air running are some examples of the “instant” ways to make cash on Runescape. It’s not nearly as fast at making gold as some of the more advanced methods described in this guide, but the difference is, there is absolutely no risk in rune running at all! Rune running is possible because high level players are always trying to gain Runecrafting XP by crafting runes. However, they need people to bring them rune essence to make the runes.
Air Running - Non-members and Members
Air running is basically the same as Law Running, except that it can be done by non-members as well as members. You'll need to be on World 16 and pay visits to the Air altar. You should have 25 Rune essence in your inventory when air running (you can buy rune essence fast on world 1 or world 2). How much gold you will make from air running depends on your timing and luck.
1. Go to Falador East Bank and withdraw the 25 Rune essence.
2. Make the run south to the Air altar.
3. Once you get to the alter, look for people saying "open." Trade with them. On the trade screen, offer 25 Rune essence. The other player will trade you 25 noted essence and some gold for your effort (To make sure you're getting a fair amount of gold, check around to see how much other air runners are getting paid).
4. Head back to the Falador East Bank and repeat the process until you get enough money.

Law Running - Members Only
The world where most people will law run is World 66. The line of people will show you the path to the law altar, but the problem is that there may be too many people competing around. Again, how much gold you actually make depends partly on your timing and luck.
First, make sure that you have no armor or weapons equipped while law running. Also, wearing boots of lightness or the hunting skill capes can help speed up sprinting and decrease the time it takes to complete each run.

You will need at least 27 Pure Essence to law run. If you don't already have 27 pure essence, then buy it!

1. First, go to the Draynor bank and withdraw 27 essence from your bank. This essence must not be noted.

2. Head to Port Sarim and talk to one of the monks. They will ship you to Entrana, where the law alter is located.

3. Once you get to the alter, look for people saying "open." Trade with them. On the trade screen, offer your 27 essence. They will trade you 27 noted essence and 27 law runes for your essence!

4. Head back to the Draynor bank, and repeat the law running process as many times as you can. After you acquire a good sized stock of law runes, sell your law runes for the current market price.
If you're a non-member, air running will be your only option. However, if you're a member, experiment to see which method works the best for you.
