You can run as many events as you like at any one time. 

If you do have multiple events running at the same time, you might like to create your own Organiser Page, which lists all current events and is updated automatically. The URL always remains the same so you can send ticket purchasers here to see all events. Please contact us if you have any questions and we'd be happy to help.
