Intro
The Ismanon channel walks through ME ENFRENTO AL ENTRENAMIENTO DE UN ATLETA OLIMPICO ESPAÑOL!!🥇 with a sharp training session that’s worth studying. We’ve distilled it here so you can replicate the workout today—head to the full video to see it performed and get the full context.
Key Points
- The main session consists of 3 × 3 km intervals run at approximately 10 k race pace—typically 3:25‑3:30 min/km or about 17 km/h.
- Intensity is dialed in by measuring lactate after each repeat, aiming for a 2‑3 mmol/L range to maintain steady state throughout.
- Open the first repeat at a controlled rhythm, then push the final one slightly harder to create progressive overload.
- Rest periods last around 1 minute 30 seconds—light jogging or walking to recover between efforts.
- The session bookends include a 6 km easy run (with a handful of short technique strides) to prepare, and a 2 km easy jog afterward to bring the heart rate back down.
Workout Example (adapted for most runners)
Warm‑up: 6 km easy (≈5:30‑6:00 min/km) + 4×100 m strides
Main set: 3 × 3 km
• Interval 1: target pace ~3:30 min/km (≈17 km/h) – keep lactate 2‑3 mmol/L
• 1′30″ easy jog recovery
• Interval 2: same pace, adjust up/down based on lactate reading
• 1′30″ recovery
• Interval 3: try to finish a little faster (e.g., 3:25 min/km) if lactate stays in range
Cool‑down: 2 km easy (≈5:30‑6:00 min/km)Without a lactate meter, rely on feel: begin at a pace that feels challenging but controlled (roughly 80% of your 10k max effort), then push the final repeat slightly harder.
Practical Tips
- Treadmill or track work helps keep paces consistent and measurable.
- If you own a lactate meter, test your blood after each interval to confirm you’re hitting that 2‑3 mmol/L window.
- Tweak your speed up or down by 0.1‑0.2 km/h each round depending on your lactate numbers.
- Stick with the 1:30 recovery window—long enough to shed some metabolic stress, short enough to maintain the intensity.
- Stay hydrated throughout, and if you supplement, the creator incorporates citrulline‑malate (2‑4 g) for support.
Closing Note
Try this 3×3 km lactate‑focused session and adjust the targets to fit your 10 k or marathon goals using the Pacing app. You’ll strengthen your ability to sustain harder efforts and raise your lactate threshold. Each interval deserves your full attention.
