ISOM2000 – the scale issue 2
The reasons for the decision to permit only scale 1 : 15 000 in junior and elite competitions over the classic distance are the following disadvantages of maps at 1 : 10 000:
Route choice problem:
Remote alternative routes are not recognised with a long leg between two controls.
Long leg overview problem:
For long legs over 2 km it is hardly possible to keep an overview of more than 25 cm on the map while running.
Map size problem:
Elite routes up to 20 km long require very large map formats, which can hardly be handled in the competition.
