70.3 & IRONMAN RACE PROGRESSION SYSTEM

Stop sacrificing your life for 18-hour training weeks. Build middle- and long-distance speed, bulletproof pacing, and T2 durability on a structured 7–11 hour weekly system.

The Long-Distance Training Trap

Most age-groupers preparing for a 70.3 or Ironman fall into the same exhausting cycle:

Junk Volume Over Structure: They stack endless low-quality hours onto their calendar, believing “more is better” until shoulder impingement, Achilles tightness, or family burnout hits.
The Disconnected Swim: They follow generic pool drills written by non-swimmers, entering T1 fatigued, bloated from swallowing water, and down on energy.
T2 Leg Breakdown: They ride too hard or too flat, leading to ruined quads and a painful 21k/42k survival shuffle off the bike.

Stealth 70.3 & Ironman Squad gives you a precision periodisation system that maximises every single session—so you arrive at the start line strong, fresh, and race-ready.
