The GPS trace above can be compared to a gmap-pedometer map below. I didn't run exactly according to plan, but the distance estimate is good to within ~5 % anyway.
6640 m jog in 45 min 38 s, at a leisurly average pace of 8.7 km/h.
It's funny how in October when it's + 4 C and raining snow/water horizontally you can have this route and the parks all to yourself and hardly meet anyone during the run. Today it's sunny and +20 C and the scene is very different. Every imaginable species of urban park-dweller (and their dog!) is out and about. Jogging in June has much less of a "Hyvä on hiihtäjän hiihdellä" (Finnish skiing poem by Eino Leino) feeling to it compared to October!
Nokia Sports Tracker can be used on my N95 to keep track of speed, distance, time etc.
