The event was founded by Don Mann and his "Odyssey Adventure Racing" team. The first Double Ultra Triathlon was held at Virginia Beach, moved the following year to Colonial Beach (Triple UT was added) and in 2001 to Lake Anna State Park. Steve Kirby who was part of the OAR-team acquired the event in 2005 and organizes it, since 2014 together with Teri Smith, anually. Next to the Double Anvil (22 editions so far) and Triple Anvil (19) a Qunintuple Anvil (5) was added in 2012. The Quintuple in per day-format (2) is hosted since 2016.
