I am 1 of the fellow 138 people taking part in the latest Gold speed run which is organised by Jonathan Kenins owner of Massive Gold Blueprint. Its day 12 so far and its getting better with each passing day. My total gold aquired between horde and alliance has passed 80k (this is taken from the Total Gold aquired figure from the wealth statistics)
I have made roughly 24k just from selling vendor pets and vendor recipes alone. Follow my forum post for regular updates which includes great deals i made, tips for others, screenshots and even my exported beancounter data.
Still Patch 4.3 to unfold and also another 18days to go.
