About this race
The Fastlane Summer Edition Half Marathon follows a two-loop, entirely paved course along the Grand Canal and the perimeter of Grange Castle Business Park in Clondalkin. The route features long, straight sections, maintaining a predominantly level profile throughout. The start and finish lines are located in the green space beside the Grand Canal, accessible via Fonthill Road North.
Course profile & record eligibility
World Athletics record-eligibility rules cap net elevation loss at 1m per km of race distance, and require the start and finish to be no more than 50% of the race distance apart — both meant to stop a course gaining an unfair edge from downhill grade or a point-to-point tailwind. This is based on this course's recorded elevation and GPS data, not an official measurement or certification.
