A 10-week, 5-day-per-week plan for high schoolers new to structured training — first cross country season, first track 5K, or first road race.
This plan is for a high school athlete without a structured running background: a first-year cross country runner, an athlete crossing over from another sport, or anyone whose "training" so far has been whatever practice happened to be. Five days per week, two quality sessions, and a volume ramp that respects the fact that tendons and bones adapt slower than lungs.
Everything is prescribed in minutes at an effort, not miles at a pace. Here's why: a 5-mile easy run can be cheated — run it faster and you're done sooner. Forty minutes can't be cheated. Run faster and you're simply running harder for the same forty minutes, which defeats the whole point of an easy day. About 80% of your weekly time stays at conversational effort — that's where the aerobic engine that carries the last mile of a 5K gets built.
The Weekly Skeleton
| Day | Session | Purpose |
|---|
| Monday | Easy run | Volume |
| Tuesday | Fartlek | Speed development |
| Wednesday | Easy run + 4 strides | Recovery + mechanics |
| Thursday | Repeat intervals | 5K-specific fitness |
| Saturday | Long run | Endurance base |
The 10-Week Progression
| Week | Total Time | Tuesday Fartlek | Thursday Intervals | Saturday Long Run |
|---|
| 1 | 180 min | 6 x 1 min on / 2 min easy | Strides only | 45 min |
| 2 | 195 min | 8 x 1 min / 2 min | 2 x 4 min hard / 4 min easy | 50 min |
| 3 | 210 min | 8 x 1 min / 2 min | 3 x 4 min / 4 min | 55 min |
| 4 | 185 min (easy week) | 6 x 1 min / 2 min | Strides only | 45 min |
| 5 | 225 min | 10 x 1 min / 90 sec | 3 x 4 min / 4 min | 60 min |
| 6 | 245 min | 5 x 2 min / 2 min | 3 x 4 min / 4 min | 62 min |
| 7 | 260 min | 6 x 2 min / 2 min | 4 x 4 min / 4 min | 65 min |
| 8 | 280 min (peak) | 6 x 2 min / 2 min | 4 x 4 min / 4 min | 70 min |
| 9 | 230 min | 5 x 2 min / 2 min | 3 x 4 min / 4 min | 55 min |
| 10 | 160 min + race | 6 x 1 min / 2 min | 4-6 strides (Thu) | 5K race! |
Unlisted time is split between Monday and Wednesday easy runs. Every quality day includes a 12-15 minute easy warmup finished with 4-6 x 20-second strides before the first hard segment, and a 10 minute cooldown — all of it counts toward the weekly total. The workout does not start until the strides are done: they bridge the gap between jogging and race-speed mechanics, and they're the cheapest injury insurance in this plan.
The Two Signature Sessions
The fartlek builds speed without a track: surge to a strong effort — roughly what you could race for 15 minutes — for the "on" segment, then float genuinely easy. Grass, roads, trails, anywhere.
The 4-minute repeats are the backbone of this program: 4 minutes at a hard-but-controlled effort (about the pace you could race for 10-12 minutes), with a full 4 minutes of easy jogging between. Three to four repeats is the target zone. The standard is honesty: the final repeat at the same effort as the first, finishing with the feeling that one more was possible. This workout teaches exactly what a 5K demands — sustained discomfort with control.
How to Run This Plan
- Easy means easy. The freshman mistake is running every day "medium." Medium builds fatigue, not fitness. If you can't hold a conversation on Monday and Wednesday, slow down — yes, even slower than feels cool.
- Strides are free speed — and they open every workout. Four to six relaxed 20-second accelerations before Tuesday and Thursday's hard running, plus four after Wednesday's easy run. They sharpen mechanics without costing recovery — here's why they work.
- The easy week is training. Week 4's drop is where the previous three weeks' work gets absorbed. Don't add to it.
- Pain rule. Soreness that fades as you warm up is normal. Pain that sharpens as you run is a stop sign — take days off early, not weeks off late.
- After this plan, you're ready for a real volume progression. See our high school mileage guide for the multi-season roadmap.
Race Week
Week 10 mirrors our 5K taper guide: volume drops by almost half, intensity stays as short touches. Set your goal from Thursday workouts, not hope — if 4 x 4 minutes at 5K effort felt controlled in week 8, you're fit.
