This is a practical guide to running an Ironman-distance triathlon (3.8 km swim, 180 km bike, 42.2 km run) as a wellness challenge stretched across a week, a month, or a full summer so almost anyone can finish it. It gives the exact points conversion that keeps the three sports fair (10 points per km swimming, 1 per km cycling, 4 per km running), the canonical targets for Sprint, Olympic, Half, and Full Ironman, and a pacing breakdown for every reasonable time window. Positioned as a "niche challenge" for the already-engaged slice of a workforce — not a replacement for the steps, minutes, and distance challenges that drive broad engagement.
