Britax launches the  first “MARATHON” convertible car seat with LATCH in August 2002. It was the first  Britax high-weight capacity seat for children up to 65 pounds. It was only one months later that LATCH anchors became a standard.


In 2004 Britax called their new seat as Marathon G1, late in 2004 they launched Marathon Crimson, sorry for the picture quality but these are the only we can find.
