Walter Liniger, 69 years young is a strong runner from Switzerland. He ran his first race at age 7, his marathon PR was set at 2:38 in 1988. For many years he trained mostly at a high intensity. In his late sixties he discovered MAF training. His goals changed now not to chase the fastest times but to finish a race in healthy conditions and enjoying the journey.  Recently he ran his first Ultra of 100km at the age of 68. We discuss his running journey and things he has learned along the way.
