The Port Macquarie Bike Leg: 180 km of Rollers, Chip-Seal and the Matthew Flinders Ramp
How to manage 1,467 m of climbing spread across constant rollers, with a 17% kicker that hits when you're at your most tired.
The Big Picture
180 km with 1,467 m of official elevation gain. Heads up: older profiles showed around 1,767 m, but the course has been updated. If you find race reports with different numbers, that's why. It's not a flat leg and it's not a mountain leg: it's a rolling course that punishes anyone who rides in surges.
The Segments
Northern section, two laps. You head out on Hastings River Drive, out-and-back on Winery Drive, then Telegraph Point and Pembrooke Road. The terrain here is constant rollers up to the turnaround before Stoney Creek Bridge. The first northern lap wraps up around km 103, near transition: that's your first mental checkpoint. If you get there already on the limit, the rest of the day will make you pay.
Southern section, two laps. Ocean Drive toward the Tacking Point lighthouse, turnaround at Lake Cathie and Greenmeadows Drive. More coastal terrain, potentially exposed to wind.
Matthew Flinders Drive. The "infamous" climb heading back toward Westport Park. Short, but with pitches around 17% according to independent profiles. It comes late in the day, when you've already got more than 150 km in your legs.
What to Do: Gearing
Run easy gearing. Recommended minimum: 34x30, or a compact with a wide-range cassette. On a 17% ramp after 160 km, a short gear is the difference between pedaling seated at a decent cadence and pushing watts you'll pay for on the marathon. Test your gearing in training on a similar ramp: if you don't have one near home, simulate it with standing starts uphill at low cadence.
What to Do: Pacing
The rolling terrain at Telegraph Point and Pembrooke demands steady power output. Train your power pacing on false flats and rollers, not just on flat roads: the classic mistake is pushing 20-30 watts over target on every little ramp and "resting" on the descents. Over two laps, that pattern burns your race. Set a power cap for the short climbs and stick to it. On Matthew Flinders, don't burn watts: ride it conservatively, even if it costs you 30 seconds.
What to Do: Anti-Vibration Setup
The road surface in the area is chip-seal, flagged as buzzy in athlete reports. Three concrete countermeasures:
- Wide tires and moderate pressures: don't pump them to the max. On rough surfaces, lower pressures roll better and fatigue your muscles less.
- Thick bar tape or a double wrap on the extensions.
- Check that bottles and bottle cages hold: on chip-seal, bottles launch. Test your full setup on a rough road before race day, at race speed.
Wind and Weather
Mild spring weather: average highs of 24°C, lows of 13°C. The start is cool: consider arm warmers or a light gilet to shed as the temperature rises. Athlete reports note wind that can pick up during the day, especially toward evening: factor it in on the southern coastal section and don't chase speed, hold your watts.
The Time Limit
Bike cut-off: 10 h 30 min from your individual start. For a comfortable finish, a realistic target is around 7:15 for the leg; those aiming high ride between 4:55 and 5:25. These are rough estimates, not official data.
The Decision to Make Now
Three choices to make in your build, not in race week: (1) easy gearing fitted and tested; (2) tires and pressures tried out on rough roads; (3) a power plan with an explicit cap for the ramps. Do those three things and Matthew Flinders becomes a passage, not a drama.
