How to pace the Hobart Marathon

The Cadbury Marathon is a largely flat but gently rolling marathon, with about 146 m of climbing and 151 m of descent (a near-level net change). Pace it by even effort: ease back on the few rises and let the descents run, rather than forcing an identical pace on every kilometre.

Race conditionsPace for an ideal cool day, a typical race-day, or a warm-outlier year. Warmer conditions slow your realistic finish, and the splits below adjust to match.
AcclimatisedAcclimatised: you already train and race in conditions like these, so your body has adapted. You sweat sooner and more, hold a lower heart rate and core temperature, and barely lose time to the heat.Not yet: you mostly train in cooler weather, so a warm race hits harder, a higher heart rate, an earlier fade, and roughly twice the slowdown an adapted runner sees. It comes good after about two weeks of training in the heat.
Typical condition impactTypical January · +1.5%

A typical January morning sits around 12°C at the gun and 16°C by the finish. Adapted to conditions like these, the heat may still slow you about +1.5% against an ideal cool day. That moves your 3:30:00 goal to about 3:33:12, and the pace below already allows for it.

The coach's read

Flat and fast beside the Derwent, so the river breeze sets the day more than the gradient does. Hold an even effort, settle into a rhythm on the long riverside straights, and stay relaxed if the wind turns on the way back.

WHY  Allowing for a typical January day, that's about 5:03/km of effort the whole way, the splits below shift with the gradient, not your pace.

Ease the climbs, let the descents run, and stay relaxed through the second half.

Even-effort splits distribute your goal time by the energy cost of each gradient (the Minetti grade-cost model), not an even pace. Wind, heat, turns, and your own downhill tolerance still apply, so run the climbs by feel and stay relaxed on the descents.

Pacing the Hobart Marathon

A coach's read on how the Cadbury Marathon runs, and how to spend your effort across it.

01The course

Kilometre by kilometre

  • The climbing that matters: 10.1–10.9 km (+17 m at 2.1%), 31.3–32.1 km (+17 m at 2.1%), 20.4–21.3 km (+16 m at 1.6%). Run these by effort; your pace will and should slow.
  • Where you get it back: 12.7–13.5 km (-17 m down), 33.8–34.6 km (-17 m down), 1.4–2.4 km (-15 m down). Let these run without braking or hammering: relaxed, quick feet.
02The plan

How to pace the Hobart Marathon

  1. Read the course before race day. Flat riverside, by the chocolate factory. Flat and fast beside the Derwent, so the river breeze sets the day more than the gradient does.
  2. Pace by effort, not just the watch. Set the effort you can hold for the whole marathon, then let the pace flex with the ground: a little slower up, a little faster down, the same effort throughout.
  3. Give the climbs effort, not pace. Let your pace slow on the climbs while holding effort steady; chasing your flat pace uphill is the classic way to blow up. The biggest is around 10–11 km (+17 m).
  4. Protect your quads on the descents. Stay relaxed and let the descents come to you. Hammering downhill banks a few seconds now and wrecks your legs for the closing kilometres; the model deliberately caps the downhill benefit for this reason.
  5. Plan your finish. Hold an even effort, settle into a rhythm on the long riverside straights, and stay relaxed if the wind turns on the way back.
03Questions

Hobart Marathon, answered

Is the Hobart Marathon hilly?
It's largely flat but gently rolling, with around 146 m of total climbing over the 42.2 km and a biggest single climb of about 17 m. None of it is severe, but the rises add up.
How should I pace the Hobart Marathon?
The Cadbury Marathon is a largely flat but gently rolling marathon, with about 146 m of climbing and 151 m of descent (a near-level net change). Pace it by even effort: ease back on the few rises and let the descents run, rather than forcing an identical pace on every kilometre.
What is the hardest part of the Hobart Marathon?
The toughest climb runs roughly 10–11 km, gaining about 17 m at an average 2.1%. Flat and fast beside the Derwent, so the river breeze sets the day more than the gradient does.
Is the Hobart Marathon a good course for a PB?
It can be. It's fast enough for a personal best if you pace by effort and don't fight the rolling sections; just don't expect a dead-flat racetrack.
How much elevation gain does the Hobart Marathon have?
About 146 m of total gain and 151 m of loss over the 42.2 km, modelled from the official route and the SRTM elevation model.
