Intro

This is a quick summary of “Nike ZoomX Streakfly First Review - BIG Marathon Session!” from Ben Parkes. 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 Streakfly is a lightweight, neutral road shoe (≈200 g) with ZoomX foam and a unique “shank” for spring‑loaded transitions. It’s legal for road racing but not for track use due to its 32 mm stack height.
Ben uses the shoe for a 5‑10 k speed workout aimed at a 3:15‑3:20 min/km pace (≈5:10‑5:15 min/mile), perfect for sharpening marathon legs.
The session is built around k‑reps (1 km repeats) with short walking recoveries, followed by easy mileage to tie the legs together.

Workout Example

6 km easy warm‑up

4 × 1 km @ ~3:15‑3:20 min/km (2‑min walk recovery)

4 km easy jog (to keep legs loose)

4 × 1 km @ ~3:15‑3:20 min/km (2‑min walk recovery)

4 km easy jog (cool‑down)

*If you’re newer to the pace, start at 3:30‑3:35 min/km and work down.

Practical Tips

Use a watch or the Pacing app to set lap intervals of 1 km and a 2‑minute walk between reps.
Focus on a high cadence (≈180–190 spm) and minimal ground‑contact time to maximize the shoe’s spring.
If the shoe feels a bit roomy, try half‑sizes in‑store; the shoe’s snug fit helps lock the ankle.
Keep recovery walking brisk but short – 2 minutes is enough for recovery without losing momentum.

Closing Note Give the Streakfly‑based 1‑km repeats a try in your next speed session and feel free to adjust the paces to match your own fitness using the Pacing app. Happy running, and see you on the road!
