What we changed

Long-run progression clamped at +20% week-over-week (per Galloway 10% rule, see /methodology). Back-to-back weekend long runs from week 8. Fueling rehearsal protocol: 60g/h carbs on every run >90min, tested 8 weeks before race day. Strength endurance 1×/week protected even in peak weeks.

Illustrative result

Finished in 5h33, ran continuously through km 42–50 where previous races collapsed. No bonk, no GI issues. Ranked top-30% of age group.

Illustrative outcome
W/kg climbing: 3.6 → 4.1
Goal
Hold 4.0 W/kg up the final 25-minute climb at La Marmotte without blowing.
What we changed

Sweetspot-block periodization (3 weeks loading + 1 deload). Threshold work in week 6–8 as VO2max bridge. Climbing-specific sessions: 4×10' over-unders simulating Alpe-d'Huez gradient changes. Heat acclimation week 9 (45-min easy rides at 32°C indoor).

Illustrative result

Reached the summit holding 4.1 W/kg average for the final climb. FTP +18W, weight stable, watts/kg improved by 8%.

Postpartum runner · Return to racing
20 weeks
Illustrative outcome
10K: 42:18 (pre-pregnancy PR: 42:56)
Goal
Rebuild from week-6 postpartum to a competitive 10K — first race back after 14-month break.
What we changed

Pelvic-floor cleared progression: weeks 1–4 walk-run intervals, weeks 5–10 continuous Z1–Z2 only, weeks 11–14 strides + Z3 reintroduction, weeks 15–20 tempo + race-pace work. Cycle-phase logging integrated — heavy quality sessions scheduled in luteal-phase-safe windows. Sleep-quality-gated readiness (the engine canceled 4 sessions in the first 12 weeks when sleep <6h).

Illustrative result

Completed 10K at 42:18, 38 seconds faster than her pre-pregnancy PR. Zero pelvic-floor symptoms throughout. Resumed weekly speed work by week 14.

ATH-S65
Senior runner · Maintaining PR at 65+
16 weeks
Illustrative outcome
10K: 49:14 (age-group podium)
Goal
Hold sub-50 min 10K through the 65-69 age group transition — a pace 18 months of unstructured training had been steadily losing.
What we changed

Master's protocol applied (per /methodology iter 100): quality sessions spaced 72h apart instead of 48h, easy days extended +15 min for aerobic durability, 2× weekly strength + mobility protected as priority sessions even in peak weeks. Body Battery threshold for hard work raised to 65. Heat acclimation block week 12 ahead of summer race.

Illustrative result

49:14 official 10K — first age-group podium in 5 years. Threshold pace held steady at 4:55/km. Zero soft-tissue flare-ups across the build.

Couch-to-5K · True beginner
9 weeks
Illustrative outcome
First continuous 5K: 31:42
Goal
Run a continuous 5K from zero running history. Wanted to finish a local park-run with friends, never been on a treadmill.
What we changed

Galloway run-walk progression (per /methodology iter 87): weeks 1–3 build to 60-sec run / 90-sec walk × 8, weeks 4–6 ratio shift to 3-min run / 1-min walk, weeks 7–9 continuous 30-min easy runs. Wellness-gated readiness with conservative thresholds — sleep <6h → session auto-converted to walk. Strength endurance 1×/week from week 2 onward.

Illustrative result

Completed 5K continuously at 31:42 in week 9. No injuries. Reported "loving it" in week-12 follow-up and immediately enrolled in a 10K plan.

Sprint triathlon · First-timer
12 weeks
Illustrative outcome
Sprint tri: 1:34:12 (target 1:45)
Goal
Finish a local sprint triathlon (750m swim / 20km bike / 5km run) — never combined the three disciplines, comfortable runner only.
What we changed

Three-discipline scaffolding: weeks 1–4 swim technique focus (drill heavy, pool sessions only), weeks 5–8 brick introduction with 30-min bike → 15-min run, weeks 9–11 race-pace bricks + open-water swim transition rehearsal, week 12 taper per iter-87 methodology. Strength endurance 1×/week protected throughout. Fueling rehearsal NOT prescribed (event <90min, per iter-100 fueling principle).

Illustrative result

Finished in 1:34:12 — beat self-imposed 1:45 cut-off. Open-water transition rehearsed 4× before race day eliminated the panic that wrecks first-time tri athletes. Already signed up for an Olympic next year.

Gravel cyclist · Endurance build

Illustrative outcome
200km gravel: 9h22 (no walking)
Goal
Complete a 200km gravel event with 3,500m of climbing — previous 150km attempt ended with a 90-minute walk at km 130.
What we changed

Polarized 80/20 distribution per iter-87 methodology — most rides Z1-Z2 with one weekly Z4 threshold session. Long-ride progression clamped at +15% week-over-week (Galloway adapted for cycling). Fueling rehearsal at 70 g/hr carbs on every ride >90min from week 4. Heat acclim block in weeks 11-12 ahead of summer event date.

Illustrative result

Finished in 9h22 with negative split (faster second half by 8 minutes). No bonk, no GI issues. HR drift on the final climb stayed under 5% — the metric that flagged the previous attempt's collapse.
