The Brain
Your profile powers every tool. Update a threshold, log a race, or change your weight once — plan, simulator, and nutrition all synchronise automatically — your training load, race pace, and fuelling stay aligned.
Precision triathlon training. Every tool connected — workouts, race simulation, nutrition, and planning. Built on the conviction that nothing should be left to guesswork.
Measure and refresh your swim, bike, and run thresholds (CSS, FTP, FT). Field-test protocols that keep zones and training targets honest.
Generate a structured swim, bike, run, or strength session in seconds. Power, pace, or perceived effort.
Enter your thresholds. Get a realistic finish time and pacing targets for any triathlon distance.
Calculate your carb and fluid needs per discipline, per hour, for your specific race distance.
Dial in front and rear pressure based on your weight, bike, tyre width, and road surface.
Triathlon videos, podcasts, and articles — curated daily. Separate from training logic, still in one place.
Built by an athlete. Thirty years in the sport.
Build your plan →Your profile powers every tool. Update a threshold, log a race, or change your weight once — plan, simulator, and nutrition all synchronise automatically — your training load, race pace, and fuelling stay aligned.
Distance, date, and weekly hours in — structured swim, bike, and run sessions on your plan feed, with targets in min/100m, watts, and min/km. Base, Build, Peak, and Race week; volume adapts when fatigue demands less.
