An example of how a poll may be used to vote for which races should be included.
Vote for two of the following 10K races to be in next years Championship.
Note this is also a binary poll - each choice is restricted to an "on / off" type answer. In this case you are also only allowed to select up two choices. Polls can have a fixed start / finish date - polling is only allowed in between these dates. I've set the duration here for 1 week for a test.
