I was born in 1970 and never used to be very athletic.
In 2005 I picked up running, but not seriously and only when the weather was nice.
In 2007 it all changed.
I got infected with the idea of running the Two Oceans Ultra Marathon (56 km, Cape Town, South Africa), and since then I ran (until Dec 2016) 15 Ultra Marathon races and more than 20 standard Marathon races (Axel’s running race overview).
