After months of training, science teacher Michael Armstrong will compete in the Ironman World Championship in Hawaii on Friday.

The Ironman Triathlon competition consists of a 2.4 mile swim, a 112 mile bicycle ride and a 26.22 mile run. The events are raced in that order without a break between events. The athletes usually have between 15-17 hours to complete the events. The competition is one of the physically hardest competitions in the world.

The Championships are live streamed at http://www.ironman.com/triathlon/events/americas/ironman/world-championship.aspx#/axzz5SuAF3tWX

The competition will start at around noon central time. Tune in and show Armstrong support.
