Course breakdown

Miles 0 to 3: Start and settling in

The race starts on Chesterfield Avenue, one of the main thoroughfares through Phoenix Park. The course travels along wide, tarmac avenues and through wooded areas, passing landmarks such as the Papal Cross and Chesterfield Avenue. The terrain is rolling from the start, but don't get carried away by the atmosphere. The course gets progressively tougher.

The environment is traffic-free with strong crowd support, especially near the finish area close to the Phoenix Monument. The opening miles are your chance to settle into your target pace, ideally by following one of the pacers if their tempo matches your goal.

Miles 3 to 6: The heart of the challenge

This is where the course reveals its steady climbs and rolling sections. The profile isn't flat. Each rise demands extra effort, and if you've gone out too hard, you'll pay for it here.

The course stays on the park's wide roads, runnable without being tricky. Maintain a steady rhythm and don't break your flow on the false flats.

Miles 6 to 10: The finish

The final miles bring you back towards the finish area. The finish line is on Furze Road. If you've managed your effort well, this is the time to push. The crowds thicken and the atmosphere will carry you to the line.

What weather to expect

In mid-August in Dublin, conditions are generally mild. Historical averages show a maximum temperature around 20°C and a minimum of 14°C. Average precipitation is low (2 mm/day), with about 31% chance of encountering a day with notable rain. Average maximum wind speed is around 21 km/h.

Plan for lightweight kit, but keep a long-sleeved top or windbreaker just in case the wind picks up. Hydration remains important: even though temperatures aren't scorching, the effort over 16 km requires good fluid management. Make sure to hydrate well before the start and take advantage of water stations on the course.

Race strategy and tips

Pacing strategy

Don't start too fast. Use the provided pacers (70, 80, 90, 100 minutes) to lock into a realistic tempo from the gun. The undulating course punishes overzealous starts. Aim for a steady pace, slightly below your lactate threshold, and let the rhythm carry you.

Nutrition and hydration

Over 10 miles, hydration is crucial but nutrition can remain light. If your race will last more than 75 minutes, pack a gel or take a few sips of energy drink. Drink regularly, without waiting until you're thirsty.

Pitfalls to avoid

The main trap is underestimating the climbs. The terrain features several steady climbs that test endurance. Don't break your effort on the rises: ease off slightly if necessary, but maintain a smooth cadence. The other classic mistake: relying solely on the flat opening minutes. The course gets tougher in the middle, so save some reserves.

Training for this course

Build fartlek runs and short to medium hill sessions into your training. Phoenix Park isn't a course for records, but it rewards those who can manage pace variations. Work on your endurance through runs of 12 to 18 km with intensity changes.

What makes this race special

Originally from Galway, Frank Duffy was instrumental in re-forming the Civil Service Harriers & Athletic Club in Phoenix Park after the Civil War in 1925. He devoted his life to athletics and trained many athletes, including two Olympians, Noel Carroll and Des McGann. He notably celebrated his sixtieth birthday by running 60 miles in Phoenix Park. The race bearing his name has perpetuated this spirit for decades.
