Intro

Here’s a breakdown of This 5-Mile Test Will Reveal Your Real Fitness Level by Lee Grantham. The video delivers solid guidance. The condensed version is below so you can run the workout today. Watch the full video for context and coaching cues.

Key points

• Consistent testing removes guesswork, builds discipline, and gives you a true measure of progress.
• The core test: 5-mile (8 km) uphill effort at a controlled heart rate (roughly your marathon HR, around 170 bpm). Manage effort, don’t chase pace.
• Interval versions work too: 10 x 1 km or 20 x 400 m, each with exactly 60-second recovery. Use the same distances, reps, and rest each time for fair week-to-week comparisons.
• Log average pace, individual rep effort, and heart-rate recovery. These reveal fitness shifts and weak spots.
• Uphill repeats build posterior-chain power, refine form, and carry over to flat performances.

Workout example

5-mile (8 km) uphill test:

1. Select a familiar hill with a 5-6% gradient (some grade variation is fine).
2. Warm up with 10-15 minutes of easy running.
3. Run the 5 mi/8 km at steady effort. Target an average heart rate within ±2 bpm of your marathon HR (say, 170 bpm).
4. Note finish time, average pace, and post-run heart-rate recovery.

Alternative interval test: 10 x 1 km:

• Hammer each 1 km rep (near-maximal effort), 60 s rest, 10 reps total. Keep recovery at exactly 60 seconds.

Alternative interval test: 20 x 400 m:

• Sprint 400 m hard, 60 s rest, 20 total. Scale reps over time as fitness improves (start at 10, work toward 20).

The Pacing app handles all three formats and lets you adjust paces or zones to your current ability.

Closing note

Run the 5-mile uphill test this week and collect your baseline. Use the numbers to refine training. Repeat every 3-5 weeks.
