RUNNING POWER Comparison - Polar Grit X vs. Stryd Wind: Part 2 - Ryan Clayton

Intro

This is a quick summary of RUNNING POWER Comparison - Polar Grit X vs. Stryd Wind: Part 2 from Ryan Clayton. 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

• Power‑based intervals are ideal for short VO₂‑max work (≈3 min) because heart‑rate lag is too slow.
• Build the session in TrainingPeaks using a % of Functional Threshold Power (FTP) – warm‑up at ~25‑28 % FTP, hard intervals at 100‑215 % FTP, easy jogs for recovery.
• Export the workout to the Apple Watch (Stride app) for audio cues and on‑screen power targets.
• The Polar H10 chest strap provides HR data, while the Polar Grit X and Stryd give slightly different power readings – expect some lag on the wrist‑based Polar.
• Use the data after the run to see how the two meters compare for power, cadence, and distance.

Workout Example (≈43 min total)

1. Warm‑up – 20 min at 25‑28 % FTP (easy, steady effort).
2. Main set – 4 repeats of:
   • 3 min hard at 100‑215 % FTP (focus on power, aim for ~270 W on Polar).
   • 1.5 min recovery easy jog or walk.
3. Cool‑down / Recovery – 5 min easy running. All intervals are delivered via the Apple Watch, which will announce start/stop cues and display target power zones.

Closing Note

Give this power‑driven interval session a try today – and feel free to adjust the paces, durations, or % FTP to match your own fitness level using the Pacing app. Running with clear power targets can make those short, hard efforts feel more controlled and effective. Happy running, and don’t forget to watch Ryan’s full video for the deeper analysis!
