Seven
The record stands at seven. Seven short, wabbly steps in a row, in the same direction, is the best Hannes has done so far. He takes shorter sprints - say, 4-5 steps - all the time, and even twirls sometimes. He's fast, but his endurance is not the best, it looks like.
It is amazing, though. It's hard to tell who is the happiest when he walks, the person sending him off, the one catching him, or Hannes himself. If you could bottle up happiness and turn it into energy, we could heat up a mid-sized Finnish town with one of Hannes's walks.
Seven in a row, and counting.
