BIG UPDATE but is it better than before? | Saucony Endorphin Pro 4 Initial Review | Run4Adventure - Run4Adventure

Quick summary of BIG UPDATE but is it better than before? from Run4Adventure

This is a concise recap of Lloyd’s video – watch the full clip for all the nuances and shoe details.

Key training concepts

• Race‑day interval testing – run the same workout in two different shoes to feel the performance differences.
• 10K‑pace work – six 3‑minute repeats at roughly 6:15–6:40 mi (≈9:50–10:10 km) with 1‑minute jogs.
• Progressive feel – note changes in upper comfort, mid‑foot lock‑down, and the extra “pop” from the new carbon‑plate and Power‑Run HG midsole.

Workout structure (as run in the video)

1. 2‑minute warm‑up
2. Six × 3‑minute reps at 10K pace (≈6:15 mi) – aim for a consistent effort; if a head‑wind slows you, let the time drift up to ~6:40 mi.
3. 1‑minute easy jog between each rep for recovery.
4. Cool‑down (brief jog/walk) before swapping shoes and repeating the exact same set in the new shoe.

Tip: The session totals about 12.5 mi, with the bulk of the distance run at 10K race effort. Use a GPS watch or the Pacing app to set your target pace and let the app cue you for each interval.

Practical take‑aways you can use today

• Run the same interval in your current race shoe and then in a new shoe to instantly gauge comfort, stability, and energy return.
• Adjust the pace to your own 10K time – if your 10K is 40 min, aim for ~6:24 mi (≈9:50 km) per interval.
• Focus on upper feel: the Pro 4’s stretchy gusseted tongue and softer mesh give a more relaxed fit without sacrificing mid‑foot lock‑down.
• Notice the mid‑sole “pop”: the Power‑Run HG blend adds spring, especially on the last few reps when fatigue sets in.

Closing note

Give this interval session a try—swap your shoes halfway through and feel the difference for yourself. And don’t forget to customise the paces in the Pacing app to match your own speed. For the full breakdown of shoe specs, feel, and the final verdict, check out the original Run4Adventure video!
