Build the Engine, Stay Bouncy: A Two-Week Training Framework for Winter and Summer Break
By Ralph Havens PT, IMTC | Beyond Limits Physical Therapy, Fairhaven, Washington
The goal during winter and summer training breaks is simple:
build the aerobic engine, stay healthy, and keep the legs feeling fresh and bouncy.
Here’s a framework for high school middle-distance and distance runners.
1. Keep Easy Runs EASY
Start with genuinely easy running. Think 10-minute miles, progressing naturally toward 9s and 8s as fitness allows.
- Easy aerobic mileage.
- A few relaxed strides.
- No forcing the pace.
The goal is to accumulate consistent, healthy running without digging a hole.
2. Add Sub-Threshold Twice a Week
Sub-threshold training is the foundation for building the aerobic engine.
Consider short intervals, 800s, 1,000s, or mile repeats, with short recoveries of approximately 60–90 seconds.
The key: run at a true sub-threshold effort. You can’t run these sessions too slowly. The objective is controlled aerobic development, not racing your teammates or chasing a particular pace.
Gradually build the volume as fitness improves.
3. Keep the X-Factor
Every 10–14 days, include a little faster running to maintain speed, power, and coordination.
- Fast uphill efforts with plenty of recovery.
- Fast 150s or 200s.
- Occasionally, something a little longer.
These are not exhausting workouts. Think quality, full recovery, and finishing feeling powerful and springy.
4. Every Two Weeks, Reset
After each two-week training block, take three very easy days:
| Day | Training |
|---|---|
| 1 | 3 miles easy |
| 2 | 3 miles easy + a few relaxed strides |
| 3 | 3 miles easy |
Then begin the next two-week block.
Every three or four weeks, also reduce the overall training volume for a week to allow recovery and adaptation.
The Big Picture
Two weeks of building, three days of very easy running, then another two-week block.
Over time, gradually increase easy mileage and sub-threshold volume while keeping the running relaxed, controlled, and enjoyable.
The objective isn’t to win the workout. It’s to build a bigger aerobic engine while staying healthy, happy, and bouncy enough to keep training consistently.
And hopefully, we’ll get to Flagstaff this summer, do some of this at altitude, and have a lot of fun along the way!
What do you think? I’d love to hear how you’re structuring your training breaks.
