The Irish Life Dublin Marathon will no longer offer priority entry to past participants as it looks to increase the number of first-time and female runners.
All general entries for 2026 and onwards will be allocated through a ballot system.
According to organisers, approximately 70% of entries in recent years have gone to previous participants, while women currently make up only 36% of the field.
Previously there was a 48-hour priority entry window which allowed participants of the current year's marathon to register for the following year's marathon before the ballot opened.
That will no longer be in effect, though runners who have previously taken part will still be represented, as they can indicate if they have taken part in the Dublin Marathon since 2016 when entering the ballot.
In addition to the ballot, entries will also be reserved for elite athletes, Good for Age qualifiers, charity places, community programmes and sponsors.
If runners are unsuccessful in the ballot, they will have additional chances to gain entry through a transfer window and a refund system.
Organiser have also said that a €5 administration fee will apply to ballot entries "to cover processing and verification costs". This fee will be redeemable against the full €110 entry fee if successful, or non-refundable if unsuccessful.
Applications for entry for the 2026 Irish Life Dublin Marathon via the ballot system will open for six days on Wednesday 12 November at 7am and will close on Monday 17 November at midnight.
