ControlFreak Run
How punching works
Run up to the control point, for example the boulder, and run on – just as in ordinary orienteering.
It usually beeps before you reach the control. If it has not beeped when the control is 10 m behind you: stop and double-check that you were in the right place.
The map and the GPS are not exact
- 1Control pointThe boulder in the terrain: the control according to the runner.
- 2Control on the mapThe map's dot for the boulder: the control according to ControlFreak. The map can be slightly skewed, so the dot can be a few metres off.
- 3GPS uncertaintyAround you when you are at the boulder. The GPS may show you a few metres away.
- 4Total errorIn the worst case the errors pull in different directions and add up. If you run a few metres to the side of the boulder, that distance can be added too.
The punch is registered when the GPS shows you close enough to the map's dot.
Give yourself the best chance: run all the way to the control point.
