Critical approach:

• The downhill is a trap—resist it

• Effort: Comfortable, controlled
• Heart rate: 5-10 bpm below marathon threshold

Focus points:

• Establish consistent cadence
• Begin fuelling strategy (first gel around mile 5-6)
• Stay with a pacing group if helpful
• Run tangents to avoid adding distance

Miles 9-13: Bois de Vincennes Loop (The Quiet Miles)

Elevation: Flat to gently rolling Strategy: Maintain effort through less exciting section

What's Happening

Challenges:

• The Bois de Vincennes park loop can feel isolated
• Fewer crowds, less energy

• Course loops back on itself (can be confusing)

Landmarks:

• Heart rate: At or slightly below marathon target

Mental strategies:

• Break this section into smaller chunks
• Focus on form and breathing
• Stay hydrated at water stations
• Chat with nearby runners to pass time
• Know that the crowds return soon

The Halfway Point: Assessing Your Race

Target first half time (for 3:30:00 goal): 1:46:00-1:47:30

Passing through halfway, evaluate:

At halfway:

• Effort: Focused, purposeful
• Heart rate: At marathon target

Strategy shift:

• This is where your negative split begins
• Start reeling in runners ahead
• Each mile should feel slightly more purposeful
• Stay patient—the real push comes later

"The Seine section is where Paris races are made. You can feel the energy building as you head back toward the city centre."

Paris-Specific Strategies

Dealing with Cobblestones

Several sections feature cobblestones (paves):

• Shorten your stride slightly
• Land with a flatter foot strike
• Stay relaxed through ankles and calves
• Don't try to maintain exact pace—effort matters more

Tunnel Sections

The course passes through several short tunnels:

• GPS may briefly lose signal
• Don't panic if your watch shows weird data
• Trust your effort and perceived exertion
• Data will correct when you exit

Weather Preparation

Paris in April is unpredictable:

Fuelling on Course

Paris Marathon aid stations offer:

• Water (every 5km)
• Sports drink
• Gels (specific locations)
• Fruit (oranges, bananas) at later stations

Recommended fuelling strategy:

• Mile 5-6: First gel
• Mile 11-12: Second gel
• Mile 17-18: Third gel
• Mile 22-23: Fourth gel (if needed)

Common Mistakes to Avoid in Paris

Mistake #1: Chasing the Downhill Start

The Champs-Elysees descent is seductive. Resist it. Those first miles feel free, but your quads will pay later.

Mistake #2: Stopping for Photos

The course passes incredible landmarks—Eiffel Tower, Notre-Dame, Arc de Triomphe. Enjoy them while running, but don't stop for selfies mid-race.

Mistake #3: Underestimating Bois de Boulogne

Both parks (Vincennes and Boulogne) can feel mentally tough with fewer crowds. Prepare mentally for these quieter sections.

Mistake #4: Ignoring the Climb at Mile 18-21

The gradual climb through the western part of the course catches many runners. If you've saved energy, you'll thrive here.

Mistake #5: Not Practising on Cobblestones

If possible, include some cobblestone running in your training. It requires a different foot strike and can be jarring if unexpected.

Final Thoughts: Racing Paris

The Paris Marathon is an unforgettable experience. Running through one of the world's most beautiful cities, past iconic landmarks, and finishing on the grand Avenue Foch is a privilege.

A negative split approach lets you:

• Truly experience the early landmarks
• Arrive at the challenging miles with reserves
• Finish strong and proud
• Cross the line knowing you raced smart

The perfect Paris Marathon:

• First half: Controlled, appreciating the beauty
• Second half: Racing with purpose
