TCS Sydney Marathon Pacing Plan
Starts on Miller Street in North Sydney and crosses the Sydney Harbour Bridge around the 3km mark (closed to traffic for the race, one of the world's most photographed marathon moments) before winding through the eastern suburbs and a loop of Centennial Park, then along Mrs Macquarie's Chair in the Royal Botanic Garden with harbour views, finishing on the forecourt of the Sydney Opera House. It's the hilliest of the Abbott World Marathon Majors: total gain is substantial (300m+, including a notable climb around km 12-13), enough that pacing plans should account for real GAP variation rather than treating it as flat.

KM 0-5: The opening kilometers drop and roll: km 2 dips to 4:33/km on a -2.8% grade, km 5 to 4:37/km on another downhill. It feels like free speed, but this pace table already has you banking nothing here relative to goal effort; these numbers reflect terrain, not a gift. Hold your effort honest through the descents and resist the urge to let gravity turn this into a fast start you'll pay for later.'
KM 6-13: This stretch is where the course announces itself: km 12 climbs to 5:55/km and km 13 to 6:39/km on a 4.2% grade, the single hardest kilometer on the course. You cross 10K around 51:28 still feeling fresh, good, because the climb through 12-13 is designed to slow you on paper, not to be fought. Let the pace sag here rather than spending matches trying to hold flat pace on a real hill this early.'
KM 14-21: A long, gently rolling middle section, mostly 5:00-5:25/km, with a slight tailwind through 14-17 and 20-21 helping you along. You pass halfway around 1:50:36, right on schedule for a 3:45 finish. This is the calm before the fade really sets in, so don't chase the tailwind splits faster than the table says.'
Frequently asked questions
Is the TCS Sydney Marathon course flat or hilly?
It's the hilliest of the Abbott World Marathon Majors, with 169m of gain and 237m of loss over 42.2km. There's a notable climb around km 12-13, plus the early rise over the Sydney Harbour Bridge near the 3km mark, so the elevation profile is far from flat.
How should I pace the climb around km 12-13 on the Sydney Marathon course?
With 169m of total elevation gain packed into a course that also loses 237m, the km 12-13 climb is a significant early effort spike. A pacing plan should use grade-adjusted pace (GAP) rather than flat splits here, easing off goal pace on the climb and letting the subsequent descent bring you back toward target time.
Does crossing the Sydney Harbour Bridge affect early race pacing?
Yes, the course climbs the bridge around the 3km mark, one of the first elevation changes on the route. Starting conservatively through this section helps avoid burning effort too early, since the course has more net elevation change later, including the bigger climb at km 12-13.
Should I run an even or negative split strategy for this course?
Given 169m of gain and 237m of loss, a strict even-pace-by-mile plan will misrepresent actual effort, since the net loss (237m vs 169m gain) means the back half has more downhill than uphill overall. A GAP-based pacing plan that targets even effort rather than even pace is better suited to banking time on the descents after the km 12-13 climb.
What weather should I expect on race day in Sydney, and how does it interact with the hills?
Typical race-day conditions are around 12.9Ā°C with wind near 12.4 km/h, which is mild for marathon running. Combined with the course's substantial elevation changes, cooler temperatures help offset the extra effort demanded by the climbs, particularly the harbour bridge crossing and the km 12-13 hill.
