Anaerobic Training and Running – The Complete Guide to Speed and Finish

Anaerobic training and running—also called anaerobic run training—is about short, hard efforts where energy primarily comes without oxygen. Properly dosed, it boosts your speed, sprint, hill climbing ability, and the capacity to maintain pace in the final kilometers of a 5–21 km run. This guide provides a practical, evidence-inspired framework: what anaerobic training is, when to use it, and specific workouts you can do this week.

What is anaerobic training in running?

Anaerobic run training consists of high-intensity efforts lasting from a few seconds to about 90 seconds. Here, the body primarily relies on two systems:

• Alactic (ATP-PC): 0–10(–15) seconds
  Purpose: Explosive acceleration and top speed.
  Feels like: Maximal, but very short.
  Used for: Short bursts ("strides"), accelerating out of turns, final sprint.
• Anaerobic glycolysis (lactic): approx. 20–90 seconds
  Purpose: High speed for short to moderate duration.
  Feels like: Burning legs, increasing acidity.
  Used for: 200–600 m intervals, hill intervals, fartlek with hard segments.

Intensity keys: Use RPE (1–10). Anaerobic sessions typically fall within RPE 8–10. Your heart rate will often peak after the interval itself due to delay—primarily go by feel and quality.

Why anaerobic run training at all?

• Speed reserve: A higher top speed makes your race pace relatively easier.
• Economy & neuromuscular sharpness: Short, fast efforts improve stride, push-off, and coordination.
• Towards the end of races: Better ability to maintain pace when fatigued—from 5 km to half marathon.
• Hills and terrain: Anaerobic "surges" over hills and around turns provide tactical freedom.

When in the training year?

• Base (aerobic foundation): Very limited anaerobic training—stick to technique strides (4–6 × 10–12 sec) 1–2 times/week.
• Building phase: 1 specialized anaerobic session/week + 1 threshold/VO₂ session + easy runs and long run.
• Competition season: Maintain 1 short, high-quality anaerobic stimulus every 7–10 days for sharpness.

Specific workouts for anaerobic training and running

All sessions begin with 10–15 min warm-up: easy jog, dynamic mobility (ankles/hips), technique drills (knee lifts, butt kicks, skips), and 3–4 short strides.

1. Alactic sprints (pure speed): 6–10 × 10–12 sec maximal on grass/track. Rest 60–90 sec. Purpose: Top speed and stride length/cadence.
2. Short hill intervals: 8–12 × 20–30 sec hard uphill. Rest: walk down. Purpose: Power in push-off and low injury risk.
3. Classic track intervals: 10–12 × 200 m or 6–10 × 400 m. Rest: jog/90–150 sec. Purpose: Fast, controlled speed.
4. Anaerobic capacity by time: 8–10 × 45 sec hard / 2–3 min jog. Variation: 5–8 × 60–75 sec. Purpose: Tolerate acid and maintain technique.
5. Fartlek with anaerobic elements: 30–40 min with 30–60 sec hard every 3–4 min. The rest at an easy pace.

Volume, rest, and progression

• Total hard time per session: 6–12 min for most.
• Rest: Better too long than too short—aim for sharp speed and good technique.
• Progression: First increase repetitions, then tempo.
• Weekly dose: 1 (max 2) anaerobic sessions/week combined with easy runs, 1 threshold/VO₂ session, and a long run.

Technique and injury prevention

• Short, light strides reduce braking effect.
• Straight back, relaxed shoulders, arms close to the body.
• Use hills before flat sprints if you're new—it's gentler.
• Strength training 2×/week (20 min): squats to a chair, step-ups, deadlifts with resistance band, calf raises, core exercises.
• Recovery weeks: Every 3rd–4th week, reduce volume by 20–30%.

6-week plan – integrated anaerobic run training

Train 4–5 times/week. Adapt according to daily form.

• Week 1: Easy 40 min; hill intervals; easy 35 min + strides; long run 70 min.
• Week 2: Threshold 3 × 8 min; easy 40 min; 200 m × 10; long run 75–80 min.
• Week 3: Easy 40 min; anaerobic capacity 8 × 45 sec; easy 35 min; long run 80–90 min.
• Week 4: Fartlek 30 min; easy 30–35 min; long run 60–70 min.
• Week 5: Threshold 2 × 12–15 min; easy 35 min + strides; 400 m × 6–8; long run 90 min.
• Week 6: Easy 40 min; hill intervals 8–10 × 30 sec; easy 30 min; long run 75–85 min.

Gear, layers, and weather

Anaerobic training often takes place in changing weather—wind, showers, sweat, and breaks between intervals.

• Outer layer: Light running anorak with wind resistance.
• Base layer: Moisture-wicking technical T-shirts/long sleeves.
• Bottoms: Tights or shorts with freedom of movement.
• Details: Reflectors, cap, duffel bag for changing clothes.

BARSK designs durable training apparel with a focus on freedom of movement—perfect for anaerobic run training.

Mistakes to avoid

• Too many hard sessions in the same week.
• Too short breaks—technique collapses.
• Mixing everything on one day (strength + anaerobic + long run).
• Ignoring injury signals.

Frequently asked questions about anaerobic training and running

• How often? 1 time/week is enough for most.
• Combine with VO₂ intervals? Yes, but separate them in time.
• Does it help for a half marathon? Yes, via speed reserve and pace under fatigue.
• Will I be very sore? Reduce intensity, use hills, sleep and eat well.

Conclusion

Anaerobic training and running is your tool to become faster and more robust—if you dose wisely. Focus on quality, technique, and gradual progression. With functional clothing—e.g., running anorak, technical tops, tights, and shorts from BARSK—you can deliver high quality in all intervals, regardless of the weather. Never give up. Dig deep.
