One Lap Under a Minute

A 16-week plan from Monday, December 14, 2026 into the spring season. Geneva chases a sub-60 400m; Grant, Charissa and Steven build aerobic fitness on the same two track nights.

Every week

The weekly rhythm stays the same all season. Only the track sessions change; find them week by week in the season below.

Track session warm-up (same every time, about 25 minutes)
  1. 10 min easy jog (adults stay in Zone 2)
  2. Dynamic mobility: leg swings, walking lunges, hip openers
  3. Drills, 2×20m each: A-skips, B-skips, high knees, butt kicks, straight-leg bounds
  4. 4×80m strides, building to fast, walk back

Cool-down: 10 min easy jog and light stretching. Keep an easy or rest day between the two track sessions, and swap days around as needed.

Grant’s heart rate

Most of your runs land in the gray zone: too hard to be easy, too easy to build speed. Moving easy days down to 135–150 bpm is the biggest single change.

Heart rate zones from Strava with recent runs marked Z1 Z2 128–158 Z3 Z4 Z5 easy target 135–150 Nov 11 Zone 2 run 139 bpm · 10:25/mi Oct 28 “easy” run 165 bpm · 8:14/mi 100 200 bpm

Zones and runs from your Strava (zones are based on your max heart rate). Apple Health isn’t connected, so resting HR, HRV and VO2max aren’t included yet.

Target paces

These are my estimates from standard training ratios, not measured values. Re-check them after each test.

Off-track days

Two gym sessions a week, 40–50 minutes. Technique before load; Geneva’s school coach or a qualified strength coach should set and supervise the weights.

Gym #1: strengthGym #2: power and single leg
Goblet or back squat, 3×5–6Box jumps, 4×4 (step down)
Romanian deadlift, 3×6–8Bulgarian split squat, 3×6 each leg
Hip thrust, 3×8Single-leg RDL, 3×6 each leg
Calf raises, 3×12Bounds, 3×20m
Plank variations, 3×30sCopenhagen plank and dead bugs, 3 rounds

In the competition phase, cut to one shorter gym session and drop the heaviest sets in race weeks.
