The Victoria 70.3 bike: 90 km of rollers where momentum won't save you

The numbers

90.6 km in a single loop through four municipalities on Vancouver Island, with views of Haro Strait, the Coastal Mountains and Saanich Inlet. Official elevation gain is 928 m (3,045 ft); other measurements range between 826 and 1,128 m, so take the number with a grain of salt. Steepest recorded gradient: 7.3%. There's no climb you'd actually call a climb.

The character of the course

This is not a steady-watts course. It's constant rollers, and above all lots of corners that kill your descending speed. On other courses you'd hit 55 km/h downhill and carry momentum halfway up the next rise; here you're often braking, cornering and restarting from low speed. The result: lots of micro-surges, each one with a cost. Several race reports describe exactly this broken-rhythm feeling, more tiring than the elevation profile suggests.

How to manage your pacing

The trap is obvious: every surge puts you above threshold for 20-40 seconds, and dozens of surges add up to burned glycogen and dead legs. Practical rules:

• Set a power cap for surges and stick to it, even when you feel great in the first 30 km.
• After every corner, bring your effort back to target gradually, not with a punch.
• Keep a deliberate margin: the run is on trail with roots and rocks, and running off-road on cooked legs is much worse than on pavement.

In training, work with over-under intervals and rides on rolling routes where you have to surge often. Also practice the non-surge: exiting a corner and building back up to pace calmly is a trainable skill.

Pavement, traffic and rain

The pavement is rough in places and most of the roads are open to traffic; only some sections are closed. In wet years, reports mention very wet roads: in late May on Vancouver Island, rain is a real possibility. What that means in practice:

• Tire pressures suited to rough pavement, not track pressures.
• Genuine caution on descents with corners, especially in the wet.
• Clean lines and attention to traffic on open sections.

The cold in the opening kilometers

You come out of 16-18 °C water into air that sits at 8-10 °C in the morning. The first 20-30 minutes on the bike can be the coldest of the day, with numb hands that brake poorly. Consider gloves and socks for the first stretch, or at least a windproof vest staged in transition. Test your setup in training: getting dressed with frozen hands is slower than you think.

Aid stations and self-sufficiency

Aid stations roughly every 25 km: water, electrolytes, Maurten 100 gels and bananas. Three or four stops over 90 km isn't much: if your stomach hasn't met Maurten, bring your own products and use the aid stations for fluids only.

What to do now

• Add over-under blocks to your long rides between now and race day.
• Pick tires and pressures for rough pavement and possible wet conditions, and test them.
• Decide your cold-weather strategy for the first 30 minutes (gloves, vest, socks) and test it on a cool morning ride.
• Set your surge power cap and write it on your head unit: at Victoria, the race is won on control, not enthusiasm.
