Intro: This is a quick summary of How to Run a 10k PB from This Messy Happy. 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:

Discipline and consistency (running 5‑6 days a week with steady weekly mileage) were the biggest driver of the new personal best.
Structured training cycles – macro (months), meso (blocks) and micro (each run) – let Mary focus on base endurance, speed‑endurance, and recovery.
Adding cross‑training (pilates, kettlebells) and prioritising sleep/rest helped the body adapt and stay injury‑free.
A “feel‑first” race strategy – only checking the watch at kilometer marks – let her run more relaxed and faster.

Workout example: Speed‑endurance interval (kitchovy session)

Warm‑up 10 min easy jog
3 × 1.2 km repeats at your target 10 k pace (≈ 4 min 30 s per km) with 2‑3 min easy jog recovery between each
Cool‑down 10 min easy

Run this 2‑3 times per week during a meso block focused on speed endurance.

Closing note: Try the interval session and the consistent weekly schedule, then tweak the paces to match your own fitness in the Pacing app. Believe in your ability to improve and keep the runs fun – you’ll be on your way to a new 10 k PB!
