Some spaces on the Racetrack feature Challenges. These spaces provide various Race Effects if a certain requirement is fulfilled. Some Challenges are represented on the Challenge tiles, which can be placed on the board during setup. The following rules apply to Challenges, unless stated otherwise by a specific Challenge:
If a Challenge requires that you discard something, but you don't have the necessary resources, you cannot generate the associated Race Effect(s).
When moving your Inventor Pawn multiple spaces, you cannot pause at Challenge spaces to execute them along the way. Exceptions to this rule include Glaciers and Crowds, which are automatically activated immediately when your Inventor Pawn enters that space.

If your Inventor Pawn is at rest on one of these spaces at any time during a round, you may spend a Cog to receive the Gain a Die () Race Effect.
You may do this as many times as you wish while your Inventor Pawn is at rest on on this space, as long as you have Cogs available to spend.
If your Inventor Pawn is at rest on one of these spaces at any time during a round, you may discard a die of the indicated type from your Dice Pool to immediately gain Motion equal to the number of icons indicated (some spaces on the Racetrack containing Rails generate Smooth Motion , which ignores Terrain )
If your Inventor Pawn is at rest on one of these spaces at any time during a round, you may discard a die of the indicated type from your Dice Pool to gain the number of Cogs indicated. Each player may only execute this Challenge once per game.
A Glacier is a special type of Terrain. When your Inventor Pawn enters one of these spaces, you may discard a die of the indicated type from your Dice Pool to ignore all Terrain on this tile.
If you end the Race Phase on a space with a icon, you unfortunately did not make it across the Jump and you must move your Inventor Pawn backward toward the Starting Line until you are on a space which does not feature a icon.
The moment your Inventor Pawn enters one of these spaces when travelling forward, immediately gain 5 Cogs minus 1 for each incomplete valve connection
A in your Invention.
A half-valve that shares a border with another card is still considered to be incomplete. If you have 5 or more incomplete valves, ignore the jeers of the crowds and continue on your way. This Challenge is not activated if you enter it when moving backward. In the above example: Ferdinand von Zeppelin gains no Cogs from the crowd because he has 5 incomplete valve connections.
