When you purchase a Conqueror Challenge, you will receive a join code.
This join code does not have an expiry.
However, once you have redeemed your join code and joined the challenge there is an 18 month window that you have to complete your challenge. After this point it will expire and you will not be able to post distances to that challenge, but all of your distances and challenge data will remain on your account.
If you are still trying to post distances to a challenge that has expired, please contact our customer service team and they will be able to help.
The exception to this is the yearly challenges, for example Conquer 2023. These will only be available until early in the following year. If you do not complete these challenges within this time frame you will not be able to extend.
