How far do you usually have to run to get this runners high? I sometimes run about 3 kms, but don't get it.I would recommend running or even jogging to anyone. The phenomenon of a runner's high is pretty common. I get this euphoric, pumped feeling after a run. The run itself is a strain, but it's well worth it for that feeling after a run. It's actually enjoyable after a while. Swimming is also pretty good.
