Important: What to wear: A heart and/or something red (and your usual running gear, of course - we do not want to make the people of Östermalm happy, do we?) .
Trail: obviously a City-Trail - according to weather conditions with visible or invisible trail.
BS: Yes, and it will be in a sheltered environment
Walkers: You get a map. I am laying the trail alone after work, so you lot have to follow that one, ok?
