Challenge Québec.
Race Québec City on your terms.

Québec gives you a rare chance to race a closed highway before running beside the Saint-Charles River. There is little climbing to blame for a poor second half. That makes the choice to hold your effort on the bike harder to hide.

What could you race?

I’m Tom, the coach behind Sense Endurance Coaching. Tell me where you are now and I’ll show you what a strong day in Québec City could look like.

Your age and race category help me estimate where that performance could place you. They don’t determine how fast I think you can race.

Change units

An easy-looking highway can be a difficult place to stay patient.

The swim at Bassin Louise brings you into the harbour, then the Dufferin-Montmorency Highway gives you a long stretch where it's easy to become obsessed with speed. Your half marathon follows the Saint-Charles River, not a sightseeing tour of Old Québec. Ride for that run, especially if the river air turns windy.

Bassin Louise, Port de Québec

Begin with a steady swim line

Bassin Louise offers a sheltered-looking start, but the first turn still deserves your attention. Study the final 2027 buoy line, find your breathing and resist racing the opening metres just because the harbour feels contained.

Check the revised buoy course. Let breathing settle.

Dufferin-Montmorency Highway, out

Don't bank a flattering first split

The route leaves along a highway closed for race traffic. The surface and lack of major climbs may encourage a quick split; let the forecast guide equipment choices, not a promise about whether the outward leg has a tailwind.

Hold sustainable power. Begin planned fuelling early.

Dufferin-Montmorency Highway, back

Hold the effort when the speed changes

Coming back towards the port, the same wind can have a different effect on your speed. Keep your effort steady instead of trying to recover every slower kilometre on a flat road.

Don't chase your outbound average. Leave the bike ready to run.

Saint-Charles River, outward

Take the quiet first half

The run follows the Saint-Charles River rather than making a sightseeing tour of Old Québec. Use the park corridor and any shade actually available to settle into a pace you can repeat.

Find running rhythm. Take refreshment by plan.

Saint-Charles River, return

Make the final kilometres your decision

Only increase when the opening run was controlled and the fuelling held together. The route returns towards the port; mark the final turn and aid points from the race-week map rather than guessing where your finish effort should begin.

Check your stride before pressing. Make the final pace increase earned.

What to check in race week

Find the final Bassin Louise buoys and the bike highway closures before settling on a race-day plan. Check the Saint-Charles turnarounds, aid and final approach to the port. Prepare for wind, but let the actual forecast decide which direction needs the most patience.

Build the legs.
Practise the decisions.

A finish range gives you something to work towards. The preparation is specific to this race: a steady-power highway out-and-back and a conservative opening run beside the Saint-Charles feel like one continuous piece of race execution.

I’m Tom. With Sense Endurance Coaching, I’ll build that preparation around your life, follow how you respond and adjust the work as you get closer to Québec City.
