After a disappointing race career in 2005, Lieto chose to return to work as a mortgage broker while still continuing to train. Lieto said that returning to work "...helped me balance the time and focus I put into triathlon. I still focus on training, but without the endless thinking about the next race or the next training day. It allows me to be a little more relaxed in my preparation for a race." Since 2003, Lieto has steadily worked up his finishing place at the Ironman World Championship: 13th in 2003, 18th in 2005, 9th in 2006, 6th in 2007, 18th in 2008 and 2nd overall in 2009. He is the current bike course record holder for the 2005 Ironman Canada, with a time of 4:25:26. K-Swiss is Lieto's primary sponsor.
