# Script to manipulate zoffline bot files

# Route ID can be found in http://cdn.zwift.com/gameassets/GameDictionary.xml (signature)

# Type .position in chat to find start road and roadTime, the values will be printed in console
# Choose a position where the bot passes both times at the same speed to have a smooth loop
