This website lists when events are on, and we are not involved with organising any of them. In most cases, the information we have listed is straight from the event website or Facebook page.
If you have an enquiry relating to an event (e.g. registration, registration issues, need to know what road closures there are, start times, etc) then you need to find this information on the event website and/or get in touch with the event organisers.
To do this, go back to the event you were looking at where you will find links through to the website, contact page and/or Facebook page for the specific event. Click through to one of those and contact the event organiser there.
