In his youth he was quite active and enjoyed such sports as football. At the age of 18 his interests shifted and he began to ride mountainbike. In 2002 he took part in his first 24-hour cycling event. In 2005, at the age of 22, he became the youngest person to enter and complete the 'Race Across the Alps'. In the following years he won several more 24-hour races and in 2007 he set a new Austrian record in 24-hour cycling events by riding 950 km and became the youngest Ultra World Champion at the age of 25. In 2009, on his first attempt, he qualified for the Race Across America but had to quit due to health problems after 2400 km (at that point he was in 4th place).
