Intro: Ben Is Running has a video called Improve your RUNNING SPEED with this TRACK WORKOUT (painful)—definitely worth watching. Here’s a complete breakdown to help you run this session today. Head back to the original for additional coaching commentary and technical form cues.

Key Points:

  • Built around short, high-intensity repeats (600 m, 500 m, 100 m, 400 m, 200 m) with minimal rest periods, this workout creates an intense lactate buildup that sharpens 800–1500 m speed.
  • Start with a 3 km easy run on the grass before moving to the track for your warm-up.
  • Each interval has a target pace listed below; conditions like wind or your current fitness may call for small adjustments.
  • Spike shoes are useful here for grip on the track during these shorter efforts; the coach in the video chose “dragonfly” spikes.
  • Keep 30-second jog recoveries between short repeats; allow 5–6 minutes after the longer intervals to bring your breathing back down.
  • 5K and 10K runners can include this anaerobic work once every 3 weeks to add leg speed without losing your aerobic base.
  • After the session, use recovery products like CBD to ease hamstring soreness from the lactate stress.

Workout Example:

Warm‑up: 3 km easy run (field) – easy pace

1. 600 m @ 1:27 (target) – 6‑minute jog recovery
2. 500 m @ 72‑73 s
   30‑sec jog
   100 m @ ~14 s
   5‑minute jog recovery
3. 400 m @ 57‑58 s (max effort)
   30‑sec jog
   200 m final (all‑out) – time not prescribed

Feel free to adjust the paces based on wind or fitness (for example, running 1–2 seconds slower per interval on a blustery day), but keep recovery periods as prescribed to maintain the lactate effect.

Closing Note: Test out this challenging but worthwhile track session—adjust paces based on your recent race times (the Pacing app helps with this), and you’ll feel a real boost in leg speed. Keep up with the training, and don’t forget that you can tweak the repeats to fit your specific goals. Happy running!
