Intro: This breakdown covers This Training Hack Will Get You A PB from The Running Channel. The full video is worth watching, but here’s what you need to run the workout today.

Key points

• Progressive runs start slow and build speed throughout, finishing at target race pace.
• You learn pacing discipline (no fast-start trap), build strength as fatigue sets in, and recover faster than from an all-out effort.
• Lap-by-lap pacing data lets you track each section and adjust mid-run.

Workout example

Progressive 10K (all distances in km)
1. 0-7 km at a comfortable, steady pace (~6:00/km for a 53-min 10K goal)
2. 7-10 km at goal race pace (~5:18/km), "hard but sustainable" effort

Variations:

• 75% easy, 25% hard (7.5 km easy + 2.5 km fast).
• Three sections: easy, moderate, fast.
• Add 5-10 seconds per km in each segment for a smoother ramp-up.

Practical tips

• Watch lap splits to nail target pace in the final 3 km.
• The closing push should feel like a tempo run, firm effort and controlled, not a sprint.
• After finishing, see how your legs responded. You’ll usually feel fresher the next day with progressive efforts than after going all-out.

Closing note Try this and see how it sharpens 10K fitness. Adjust paces to your targets and log it in the Pacing app.
