A review is being held into the way this year's Dublin Half Marathon was organised.
Fingal County Council says it wants to figure out what caused "significant" traffic disruption around the event last month.
It's asking people living in the Donabate area for feedback so future events can run more smoothly.
"The submissions will form part of the Review being undertaken by the Council and the event organisers, Dublin Race Series, to establish the cause of the traffic issues that created significant disruption in the area on the day", a statement on the council's website read.
Submissions must be submitted through this link before 10pm on October 27.
