Intro

A quick breakdown of “3 Miles a Day: The Simple Plan to Massive Running Gains” by Lee Grantham. The video is worth your time. Here’s the essential takeaway you can put into practice immediately. Watch the full video to get all the nuances.

Key points

• Consistency matters more than mileage. Running 3 miles (about 5 km) daily across six days, maintained over 12-13 weeks, produces noticeable improvements in 5K, 10K, and marathon performance.
• Weekly layout: Monday calls for recovery work. Tuesday is easy. Wednesday is interval training. Thursday is off. Friday returns to recovery mode. Saturday is another easy day. Sunday is the long run.
• Recovery vs easy runs: after intense efforts, recovery runs keep you in zones 1-2 and emphasize form and breathing mechanics. Easy runs, performed when fresh, stay in zone 2 and build aerobic capacity.
• Building interval work: begin with 20 × 200 m intervals (60 s rest between), then progressively extend reps while reducing count, moving through 15 × 300 m and eventually 12 × 400 m, all at 5K-10K pace.
• Expanding the long run: start Sundays at 4 miles, advance to 5, then 6. As fitness develops, plug in a 2-3 mile surge at race pace mid-run.

Workout example

Weekly schedule (distances in miles):

• Monday: recovery run, 3 mi in zones 1-2, emphasizing midfoot strike and controlled breathing.
• Tuesday: easy run, 3 mi at zone 2 intensity.
• Wednesday: intervals, 3 mi session total. Start with 20 × 200 m, 60 s between reps. Over subsequent weeks, shift to 15 × 300 m, then 12 × 400 m. Include proper warm-up and cool-down.
• Thursday: rest day.
• Friday: recovery run, 3 mi, very relaxed, zone 1 effort.
• Saturday: easy run, 3 mi, zone 2 cadence.
• Sunday: long run, progress from 4 mi to 5 mi to 6 mi (all at zone 2). As you grow stronger, plug in a middle segment at half-marathon or 10K race speed (for instance, 2 mi easy, 2 mi at goal pace, 2 mi easy).

Closing note

Try this 3-mile routine, dial in your paces through the Pacing app, and let steady weekly volume translate into race-day speed.
