Dublin Marathon
Dublin Marathon is a rolling marathon in Dublin, Ireland, held each October. A friendly city loop with steady undulation — no single big climb, but little true flat either. Late October is cool and often showery, 6-12C. With Dublin Marathon's constant undulation, pace by effort rather than the watch: even effort beats even splits here.
