The Dublin Marathon race organisers have announced that registration for the 2020 KBC Dublin Marathon will occur through a lottery system instead of the first-come, first-served online process.
They say the decision was made as a result of the increased demand for race entries.
This change comes after registration demand for the 2019 edition of the marathon could not be met despite the addition of 2,500 places.
Race director Jim Aughney said: "Many races that have more interested runners than they can accommodate have moved to a lottery registration system in recent years.
"Demand for the Dublin Marathon has never been greater, and we believe the lottery is the fairest system to offer all runners the same opportunity to participate."
Entry to the lottery will be open from the 1-30 November, with registrants will learn their entry status via SMS and email in early January.
Othmane El Goumri from Morocco won Sunday's men's marathon in a record-breaking time of 2:08:06, while Motu Gedefa won the women's race in a time of 2:27:48.
