A 10-week, 5-day-per-week plan for experienced masters runners chasing age-group podiums, peaking around 7.5 hours of weekly volume.
This plan is for the masters runner with a real training base — someone already running 4-5 days per week who wants to contend in their age group. It peaks at 440 weekly minutes, which at typical masters easy paces lands in the 40-45 miles-per-week range. That's deliberate: volume, patiently accumulated, is still the biggest lever in masters 5K performance — the aerobic system doesn't stop responding to it at 40, or at 60.
What changes with age is the cost of intensity errors, which is why this plan is strict about its distribution: 80% of weekly time at conversational effort, two quality sessions, never more. And everything is in minutes, because minutes keep you honest. A prescribed 6-miler invites the quiet cheat — run it faster, finish sooner, call it easy. Sixty minutes offers no such loophole. Run faster and you've only made the hour harder.
The Weekly Skeleton
| Day | Session | Purpose |
|---|
| Monday | Easy run | Volume |
| Tuesday | Fartlek | Speed development |
| Thursday | Repeat intervals | 5K-specific fitness |
| Saturday | Long run | Aerobic ceiling |
| Sunday | Easy run | Volume on tired legs |
Wednesday and Friday are off — or easy cross-training and strength. At this volume, the two blank days are what make the other five sustainable.
The 10-Week Progression
| Week | Total Time | Tuesday Fartlek | Thursday Intervals | Saturday Long Run |
|---|
| 1 | 300 min | 8 x 1 min on / 2 min easy | 3 x 4 min hard / 4 min easy | 70 min |
| 2 | 320 min | 8 x 1 min / 90 sec | 3 x 4 min / 4 min | 75 min |
| 3 | 340 min | 5 x 2 min / 2 min | 4 x 4 min / 4 min | 78 min |
| 4 | 300 min (easy week) | 6 x 1 min / 2 min | 3 x 4 min / 4 min | 70 min |
| 5 | 360 min | 6 x 2 min / 2 min | 4 x 4 min / 4 min | 82 min |
| 6 | 385 min | 6 x 2 min / 2 min | 4 x 4 min / 4 min | 85 min |
| 7 | 410 min | 8 x 2 min / 2 min | 4 x 4 min / 4 min | 88 min |
| 8 | 440 min (peak) | 8 x 2 min / 2 min | 4 x 4 min / 4 min | 90 min |
| 9 | 360 min | 6 x 2 min / 2 min | 3 x 4 min / 4 min | 75 min |
| 10 | 220 min + race | 5 x 1 min / 2 min | 4-6 strides (Thu) | 5K race! |
Unlisted minutes fill Monday and Sunday. Quality days carry a 15-minute easy warmup with drills, finished with 4-6 x 20-second strides immediately before the first surge or repeat, and a 10-minute cooldown — masters tendons race how they warm up. Treat the strides as the first rep of the workout, not a suggestion: they're the cheapest speed you'll ever buy.
The Two Signature Sessions
The fartlek keeps speed in the legs without a track appointment: strong, springy surges — think 3K-to-5K race feel — with genuine floats between. The discipline is repeatability: surge eight should look like surge one. When it doesn't, the floats were too fast.
The 4 x 4-minute repeats are the cornerstone: 4 minutes at hard-but-controlled effort — for a fit masters runner, essentially current 5K race effort — with a full 4 minutes of easy jogging between. Equal rest is the point: it keeps all four repeats honest instead of letting the workout decay into a fade. The progression across the block is not speed, it's composure — the same effort producing more ground, week after week. Calibrate what that effort means in pace terms with the VDOT-based Zone Calculator.
How to Run This Plan
- Count your hard minutes. At peak, this plan holds roughly 32 hard minutes in 440 total — about 7%. That's not soft; that's what allows a 50-year-old to hit Thursday's repeats at full quality all ten weeks.
- Recovery is scheduled, not earned. The easy week (week 4) and the two off days are fixed appointments. Masters runners who "feel great" and fill them are the ones who call us in week 7 about a calf.
- Strength work is part of the plan: two short weekly sessions, heavy enough to matter — the difference between a fast April and a lost June.
- Hydration compounds at volume. At 7+ weekly hours, know your numbers with the Sweat Rate Calculator, especially through summer blocks.
- If progress stalls, resist adding a third quality day — the fix is almost always sleep, easy-day discipline, or patience. Here's the full plateau diagnostic.
Race Week
Week 10 executes our 5K taper: volume drops to half, intensity becomes touches, sleep gets banked two nights out. Race on even or slightly negative splits from the 5K Split Calculator — in age-group racing, the podium usually goes to whoever fades least. With this block behind you, that's you.
