The 5K at the Yaberoo Trail Twilight Ultra is the shortest race on the programme and the only one that runs almost entirely as a loop. It is settled not in the opening kilometres but on a climb of just over 600 metres in the final third, the same climb that closes the four longer distances.
The first kilometre and a half climbs steadily from around 50 to just over 70 metres. The course then falls away in waves, broken by a short counter-rise after a little over two kilometres, and reaches its lowest point of about 30 metres before kilometre 3.5.
From kilometre 3.6 the closing climb pulls back up, recovering almost half of the lap's total ascent in just over 600 metres. From its crest around 1.3 kilometres remain, undulating but mostly downhill to the finish. At a little over 5.5 kilometres the lap also runs longer than its name promises.
The setting is the Yaberoo Budjara Trail off Burns Beach Road in Joondalup: a historic trail and limestone paths through the coastal bushland north of Perth. The distances set off progressively from the afternoon in the twilight format, and anyone aged six or over can enter. The course never rises above 75 metres, so what makes it hard is the rhythm of up and down rather than altitude.
| Start | Length | Ø | Max. | Gain | Cat. |
|---|---|---|---|---|---|
| km 3.6 | 0.6 km | 6.2 % | 8.7 % | +39 m | — |
Climb categories follow the road-cycling convention and rate the terrain itself (length and gradient) regardless of sport: Cat. 4 marks the easiest rated climbs, Cat. 1 the hardest, and HC (hors catégorie, “beyond categorization”) is reserved for the most brutal ascents. Short climbs below the Cat. 4 threshold stay unrated.
Think of the lap as two halves. Run briskly but with air in hand as far as the dip before kilometre 3.5, because after the rising start the downhill stretches tempt you into speed you cannot repay later.
The race is decided between kilometre 3.6 and a little past 4.2. An average of just over six percent with spikes near nine is not something even quick runners simply roll through. Shorten your stride, keep your breathing under control and save your kick for the crest, because that is where the real time is won.
The trap is the length: if you expect the finish at five kilometres, you still have more than 500 metres to run. Time your final sprint by the terrain, not by the reading on your wrist.

Most recreational runners need around 30 to 45 minutes for the 5.5-plus kilometres. That is a hard effort near threshold throughout, with the closing climb adding a short spike just as the legs are already burning.
Train that spike directly with hill repeats of two to three minutes at a brisk pace, each followed by a few minutes of easy running without stopping. Moving from the climb back into running rhythm is the moment in the closing kilometres when places change hands.
For the speed of the first half, one weekly run with 15 to 20 minutes at threshold is enough, ideally on undulating ground. It teaches you to carry pace through small changes of slope instead of rebuilding it every time.
Because much of the race is on trail and limestone, at least one weekly session belongs on unpaved ground so that ankles and stride know the changing surface. And since the distances only start from the afternoon onwards, it pays to move one or two hard sessions to late in the day and test what you can eat beforehand.
