Aug 13, 2025

This is a quick summary of Takumi Sen 8 - First Run from kofuzi. 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 author tested the Takumi Sen 8 with a modified Yasso 800 style workout: 10 × 3‑minute intervals at 5K race pace, with 2½‑minute jog recoveries, totaling about 13.9 mi for the day.
The shoe’s 33 mm heel stack, 6 mm drop, and 27 mm Light‑Strike Pro foam with “energy rods” (Adidas’s take on a carbon plate) make it feel springy and responsive at 5K‑10K paces.
Fit is slightly long but true to width; the arch is very narrow, which can feel tight for some runners.
A small blister appeared around the arch after the 8‑9th interval – likely a break‑in issue that should fade after a few runs.
Ideal for 5K‑10K racers; can be paired with the Boston 10 for slower‑pace training or the SL20 for daily easy runs.

Workout Example

Warm‑up: 10‑15 min easy jog
Main set: 10 × 3 min @ 5K race pace
          ↳ 2½ min easy jog recovery between each interval
Cool‑down: 10‑15 min easy jog
Total distance: ~13.9 mi (22.3 km)

Adjust the 5K pace to match your own race pace and use the Pacing app to set custom intervals.

Closing Note Give the Takumi Sen 8 a spin for your next 5K/10K workout or race – and feel free to tweak the intervals to fit your own paces in the Pacing app. Happy running!
