5 minutes of mistakes in 5 years of world championship classic events.
What is orienteering?
1000m on a track:
2:30 for a fast runner, 2:50 for someone not so fast
Only a 20 second difference, yet on a 1000m orienteering leg it would be very easy to have differences much greater than this. Much more improvement can be made by focusing on orienteering rather than pure running speed in your training.
Where do we make mistakes? Typically, 80% of the mistakes are made in the last 200m to the control.

How does one train to fix these type of mistakes?
The 2 best ways are Control Picking and Line Orienteering.

Kent Olsson rarely uses his compass. Once broke his compass in the Swedish Championships going to the first control and still finished second.
If the first leg is very long, will walk the first 500m to get in contact with the map.

There could be a good route choice behind you, but when you leave a control you typically only look at the routes between you and the next control. To find these potentially easy route choices, look over the overall course when you can.
The course setter wants us to make mistakes (it gives them great pleasure).
On long legs it is okay to pick a route off of the straight line. On shorter legs, you should be more direct.
Just before the start, have the following 2 things fixed in your mind:
Before starting a competition have a plan for route choices
Kent plans one week for mapmaking in the summer. This helps with map reading.
Do the climb early so that you are fresh entering the control.
