Irish Life Dublin Marathon pacing strategy

The course is described as largely flat, so even pacing is the plan. Use the early miles in the city and Phoenix Park to settle in. Wind and weather can matter more than hills, so run by effort if the conditions are poor.

Pacing by course section
Section	Terrain	Advice
mile 1–6	Flat city streets, then Phoenix Park	Start at goal pace or a touch slower; the crowds are dense.
mile 7–13	Out of Phoenix Park, then flat suburban roads to halfway	Keep a steady rhythm and use the half-way point as a checkpoint.
mile 14–20	Flat roads including Bushy Park (miles 17–20)	Stay patient; save energy for the last 10 km.
mile 21–26.2	Roads past University College Dublin and Elm Park to the finish	Pick up the effort slowly and finish strong at Merrion Square.

Fueling notes

The sources I used do not list gel or aid-station positions, so check the official guide. On a flat course, take a gel about every 40 minutes and one before the last 10 km.

Race-day tips

The race is held in late October, so bring a layer for the start and a plan for wind or rain
The start and finish are both in the city centre, so you can walk or take public transport
Phoenix Park is open and can be windy, so run in a group if you can
