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 Nice could look like.

Let’s build your race

Let’s build your race.

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

The mountains decide the marathon.

The mountains take time. What matters is what they leave you for the coast.

The Mediterranean · 3.8 km

Find your rhythm before you leave the sea.

A two-loop Mediterranean swim with no Australian exit means no built-in reset. Settle into a controlled rhythm from the first strokes and hold it across both loops.

Settle by 400 m. Sight consistently across both loops.

Out of Nice · first 26 km

Hold back on Les Pugets.

The opening kilometres include the climb of Les Pugets towards Saint-Jeannet. Les Pugets is uneven, averaging 3.3% but with three pitches at 10-15% in its first four kilometres. Keep the effort controlled before the longer climb.

Cap power on Les Pugets' steep pitches. Fuel before the Col de l'Écre begins.

Col de l’Écre · 18 km of climbing

The climb is long enough to punish impatience.

From km 41, the route begins an 18 km ascent via the Gorges du Loup. This is the course's defining test. Hold your planned power the entire way, not just at the start.

Ride to power, not to the athletes around you. Keep drinking through the sustained climb.

Caille and Thorenc

You’re high above Nice. You’re still racing.

At km 77 the course heads onto the Caille and Thorenc plateaus, genuinely new terrain even for athletes familiar with prior editions. Stay controlled here before the descent to Gréolières.

Stay on the fuelling schedule at the km 80 personal aid station. Manage effort on any remaining rolling terrain.

Through Gréolières

Recover without switching off.

The downhill to Gréolières through the Clues de Gréolières offers real recovery after the climbing. Stay alert on the technical sections rather than treating it purely as a rest.

Brake early into technical sections. Use the descent to recover, not to coast blindly.

Back to the coast · 180.2 km in total

Return with a marathon left in your legs.

The final kilometres bring you back towards Nice and the coast. Finish planned nutrition and let cadence rise before the transition.

Finish the planned bottle. Let cadence rise before T2.

Promenade des Anglais · 42.2 km

Flat doesn’t mean forgiving.

The run heads towards Nice Airport and back, four times. Use the aid stations from the first loop, around every 1.8 km. Waiting until you feel hot means you’re already catching up.

Through the first three loops

Loop one along the Promenade des Anglais

The run along the Promenade des Anglais, out towards Nice Airport and back, is often hot in the Mediterranean sun. Use every one of the aid stations, placed every 1.8 km, from the first loop.

  • Shorten stride out of T2
  • Use every aid station, not just the ones you feel you need

Loop two

Passing the same stretch a second time gives a clear read on how the heat and a mountainous bike are combining. Adjust for both, not pace alone.

  • Reassess pace against heat, not just fatigue
  • Keep fuelling and hydrating on schedule

Loop three

The third loop is where mountainous climbing and coastal heat combine to test the legs most. Manage effort rather than chasing a pace that's slipping.

  • Reassess goal pace honestly
  • Keep taking aid on schedule

The fourth loop

Now decide what you have left.

The final loop finishes on the Promenade des Anglais next to the beach. Check your breathing and posture before increasing pace; keep using the aid stations even if the finish feels close.

Decide the finish honestly. Save something for the beachfront finish.

What to check in race week

Check the sea conditions, wind in the mountains and forecast heat on the Promenade. Revisit your pacing and cooling plans against that forecast.

Make your finish prediction and I can send this plan to you in race week.

Build the legs.
Practise the decisions.

A finish range gives you something to work towards. The preparation is specific to this race: Training has to make the climbing sustainable, the fuelling familiar and the run possible after both.

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 Nice.
