One lap of the infamous Trail rašica mountain (ultra)running event, now in its fourth edition.
This is a real ultra run for those brave souls who make three laps, each with 1 kilometer of total climb. Look at the altitude graph to see why. Three major hills - Rašica, Grmada and Šmarna gora, along with some minor peaks to spice things up.
It was a beautiful run and walk, the weather included. Foggy and rainy and pleasantly cold.
