Melbourne 70.3's half marathon: 3 metres of elevation, zero excuses
Two laps on the Bay Trail between St Kilda and Elwood: the most honest course there is, where your final time comes down to how much you left in your legs on the bike.
A PB course
21.1 km over two laps on the Bay Trail, the foreshore between St Kilda and Elwood. Official elevation gain: 3 metres. Not flat: pancake flat. It's the kind of course where you set a pace in the first kilometre and hold it to the finish, with no climbs to manage and no descents to exploit. If you're chasing a PB over the half distance, this is the place. Plenty of race reports confirm it: a very flat, well-supported course with crowds along almost the entire route.
The flip side
Flat doesn't mean easy. First: no elevation change means the same muscles, the same stride, the same footstrike for 21 km. If you're not used to running long on dead-flat terrain, your legs will still tighten up. Second: the foreshore is as exposed as Beach Road, and the wind that kept you company on the bike doesn't disappear in T2. Third: early-November weather in Melbourne is notoriously variable, with highs around 23°C, lows around 11°C and rain roughly one day in three. You could be running in cool, windy conditions or under a biting spring sun: be ready for both.
Pacing is decided on the bike
The uncomfortable truth about this course: with only 339 m of climbing on the bike and a flat run, the temptation to push on the pedals is enormous. But a flat half shows no mercy to anyone who arrives cooked. There's no descent to recover on, no hill that justifies walking: either you have the legs or the foreshore presents the bill, kilometre after kilometre, in front of the St Kilda crowds.
Concrete strategy: hold back slightly on the first lap, 5-10 seconds per km slower than goal pace, then reassess at the turnaround. The two laps are a mental advantage: break it into four blocks of roughly 5 km and focus only on the one you're in.
Crowds and aid stations
The St Kilda area is very spectator-friendly, and the two-lap format means your supporters see you go past multiple times without moving. On the number and exact location of aid stations, the race info gives no details: check the official athlete guide when it comes out and plan your hydration accordingly, taking nothing for granted.
Benchmark numbers
Indicative run splits (rough estimates, not official data): 2h25 for a relaxed finisher, 2h05 for a mid-pack goal, 1h45 for a fast target, 1h28 for the top age-groupers. The final cut-off is 8h30 from your individual start.
What to do now
- Lock in your realistic race pace now: take your best recent standalone half marathon time, add 15-25 seconds per km and check it holds up after a hard bike leg.
- Build at least two long bricks into your prep: 60-80 km on the bike at race watts followed by 8-12 km of running at goal pace, on a flat course.
- Train for the monotony: long runs on dead-flat terrain, no variation, to get your muscles and your head used to the repetitive motion.
- Prepare a mental plan for the two laps: a pace target for the first, a decision to make at the turnaround (hold, lift, or manage).
- Test your kit in training for both weather scenarios: visor and sun protection for a hot day, an extra technical layer if you're running in rain and wind.
