Intro

This is a quick summary of Kipchoge Track Workout: Nike AlphaFly vs Nike Next% from Seth James DeMoor. It’s a great watch — we’re breaking it down so you can try the workout today. Be sure to check out the full video for all the details.

Key Points

The workout mirrors Eliud Kipchoge’s classic 15 × 1 km repeats (about 1 km each) with ~1:45‑2:00 rest between reps, aiming for ~2:46‑2:48 per kilometer.
First 10 reps were done in the Nike Next% shoe (lighter, more responsive on the track); the final 5 reps were switched to the Alphafly Next%, which felt bulkier and less stable on the corners.
The author stresses using this kind of “testing block” while not peaking for a race – a perfect time to experiment with shoe feel, pacing, and mental toughness.
Practical tip: if a shoe feels too clunky (as the Alphafly felt), switch back to a lighter shoe to maintain rhythm and confidence.

Workout Example

15 x 1 km repeats
  • Target pace: ~2:46–2:48 per km (≈4:30‑4:35 per mile)
  • Rest: ~1:45‑2:00 between reps (adjust if you need more recovery)
  • Shoes: start with Nike Next% for the first 10 reps, then switch to Alphafly for the last 5 to compare feel.

Feel free to adjust the pace based on your current fitness – the Pacing app can convert the times to your target race pace.

Closing Note Give this Kipchoge‑style interval session a try, experiment with shoe choice, and customize the paces in the Pacing app to fit your own training. Happy running, and keep pushing your limits!
