Key Points:

Ben runs a track speed session to gauge the new Saucony Endorphin Pro 3 as a potential Berlin marathon shoe.
The session focuses on short, high‑intensity reps (≈3:15–3:20 per 400 m lap) with short jogs and walk‑backs. This is a classic speed development workout, and you can learn more about the science behind it in our guide to Mastering Interval Training: Science-Backed Workouts and How a Smart App Can Personalize Them.
He emphasizes proper lane use, maintaining form, and using the shoe’s carbon plate and lightweight feel for speed work.
Practical tips include a quick run‑up before each rep, keeping reps at 5‑k pace (≈3:15-3:20 per 400 m) and using 2‑minute walk‑backs for recovery. If you’re looking to dial in that specific speed, we have more strategies in our guide on Mastering 5K Speed: Proven Interval Strategies to Cut Minutes off Your Time.
