What does plogging mean?

The practice of plogging encourages people to pick up litter while out running. So, it is not just good for your health, it is also good for the environment.

What I have just found out is the reason of the name. First, the practice comes from Sweeden and it is called "plogging" because is a mix between a Swedish word plocka upp that it means 'pick up' and jogging. 
The fact is that PLOGGING combines going for a run with intermittent stops to collect the rubbish. 
By the way, you can look at a group of runners (some friends and I -I am the one wearing a blue t-shirt) practising plogging in Torrent de Colobrers (photo above).
