Brick runs, pacing, thresholds, race execution, and footwear guidance for age-group triathletes.
The Norwegian double-threshold method is everywhere in endurance media, but no controlled study has tested it. Here's what's plausible to borrow — and what to leave to the elites.
A 5,205-runner cohort found neither weekly mileage change nor ACWR predicted overuse injury — but a single run far longer than your recent longest run did, in a dose-dependent way.
Dead legs off the bike are real and measurable — research points to altered mechanics and coordination, not just fatigue, and shows what dose of brick training actually helps.
Carbon-plated racing shoes give a real but modest running-economy boost, with huge individual variability and a new, still-preliminary bone stress injury signal — here's how to use them sensibly.
Myth: doing more brick sessions makes dead legs off the bike go away.
Myth: the same super shoe gives every runner the same boost.
Myth: never raise your weekly mileage by more than 10 percent.
Myth: copy the Norwegian double-threshold plan and get their results.
