Training for the Irish Life Dublin Marathon comes down to two things: building the right work in the weeks you have, and pacing it sensibly on the day. Our free generator counts back from race day and sets your plan length to suit how much you are running now — so you are neither under-prepared nor stretching a short build over too many weeks.
If the Dublin Marathon falls in a warm part of the year for you, plan for the heat: even a few degrees changes a realistic goal pace. Our heat adjuster shows how much to give back, and our course pacing guides cover the elevation and race-day strategy for marathons we have profiled in full.
