Where Achill Half Marathon starts and finishes
Achill Half Marathon starts at Achill Island, County Mayo. We haven't been able to place those on a map accurately enough to show one — a pin in the wrong place is worse than no pin.
These are the start and finish points, not the route. Verus doesn't hold course files for this race, and drawing a line between two pins would be a guess you might end up training on.

Training Strategy for Achill Half Marathon
10-14 weeks is a solid window for a first half marathon; 8-10 weeks is enough if you're already maintaining a baseline mileage. Build your long run up gradually rather than jumping straight to race distance.
This is a largely flat course, so most of your long runs can mirror that — flat and steady, building time on feet rather than hill strength.
Reduce overall mileage across the final 7-10 days while preserving short race-pace bursts. Arrive at Achill Island, County Mayo fresh, energized, and primed — not fit, fresh.
Lock in your target pace using the interactive splits calculator below — no official pacers are confirmed for this event, so a pace band on your watch is the more reliable option.
Test your race-day fuel and hydration plan on your long training runs, not for the first time on race day — check the Race Day Checklist below for what's actually on this course.
Half Marathon Nutrition & Fueling Plan
A normal diet is fine. There is no need to carb-load for a race of this length.
Eat a carbohydrate-focused breakfast two to three hours before the start, and stick to something you've already tested in training rather than trying anything new.
Fluid at the on-course stations is usually enough; some runners take a single gel around the hour mark.
A mix of carbohydrate and protein in the hour or so after finishing supports recovery.
