A bull market is defined as a rally of at least 20% that was preceded by a decline of at least 20%.  The current gold bull market — in which the metal is up 158.67% — has now crossed the 1,000-day mark (it currently sits at 1,008 days).  The last 20% decline for gold came from September 22nd, 2008 through November 13th, 2008 when the metal fell 22.04%.  As shown below, the median gold bull market since 1975 has lasted 418 days, so the current bull is well over double the median.  The median gain seen during gold bull markets since 1975 has been 64.03%, so the current bull is about 2.5 times the median.
