@nabilbogdan: These are 3 of my favourite interval sessions to build speed and endurance. 🏃♂️ 12 × 400 m (2 min easy jog) 🏃♂️ 5 × 1,000 m (2–3 min easy jog) 🏃♂️ 3 × 2,000 m (3 min easy jog) But remember—intervals are only one piece of the puzzle. Most runners don’t need more speed work; they need a bigger aerobic base, consistent easy miles, long runs, and proper recovery. Build the engine first. The speed will follow.
