Iron running

Iron Running was a practice in which a player trained their Mining skill by repeatedly mining iron ores. Although this practice was, for the most part, discontinued (due to the trade limit), one would give away a significant portion of the ores by trading to other players, as they were mining for XP. Frequently, the miner may trade away all 28 ores for nothing simply because it's faster than clicking drop 28 times; however, some miners would request a number of noted ores in return for giving 27 unnoted ores and possibly an amount of coins. Because the profits from serving the miner is quite low compared to Air running (approximately 1000 coins worth of gain per run), it also requires a lot more running as popular iron mining sites are far from a bank. This is an uncommon practice both in free-to-play and members alike.

Removal of Free Trade
In January 2008, after the removal of unbalanced trade, miners had difficulty trading away the ores because a low level (the usual runner) has a 5000 coin trade limit and a load of 28 iron ores is worth around 2800 coins, so every 15 minutes one full load can be taken which is much longer than the time it takes to mine 28 iron ore. A second load may be taken with less iron ore, but the effect is ruined so most of the time, the miners drop ores and let any potential runners pick them up which defeats the original purpose of Iron Running which was to quickly trade and reduce time lost via dropping all 28 ores.

Return of Free Trade
Due to the return of free trade in 2011, this practice is once again possible. Though it is possible once again due to the return of free trade, this practice is still uncommon and mainly takes place within low levels, or groups of friends.
