Hit ~80% of planned volume, never got injured, and every single long run happened: 14 → 22 → 29 → 42.4. The plan's one real rule — protect the long runs — held. Target was sub-4 stretch / 4:15 realistic. Finished 4:14:27. Called it.
Every run of the block, straight from Strava.
Five weeks from couch to 42km at 6:02/km. Aerobic memory is real. This is now the operating thesis for every challenge on this site.
Weekly volume slipped ~20% and it didn't matter. The 14/22/29km long runs were non-negotiable and they were what carried race day.
The gel schedule practiced on the 29km run executed flawlessly in the race. No wall, no bonk, negative-ish split. Rehearse, don't improvise.
Zero injuries on an aggressive ramp because easy days stayed genuinely easy and rest days were real.
Km 30–35 asked the question. "I chose this" answered it. Now it gets asked again at 70.3 run km 15.
Which is why the next challenge — IRONMAN 70.3 Belgrade — gets exactly five weeks too.
