Triathlon is three sports in one, and most athletes are left to figure out the puzzle alone: how hard to swim today, whether the bike session can wait, what to do after a missed week. Altabrio exists to take the guesswork out of that puzzle, so your time goes into training that actually fits you.
What is Altabrio?
Altabrio is an AI-powered triathlon training platform. It builds your swim, bike and run sessions day by day, based on your goals, your races, your recovery and your energy, and it explains what to do, how to do it and why each session matters. It was built with coaches who bring more than 30 years of triathlon experience, including former professional triathlete Brian Bozarth.
Whether you are preparing for a first sprint or chasing a longer distance, Altabrio is for athletes who want structure without a one-size-fits-all plan.

How Altabrio helps you train
- Clarity: each workout comes with a purpose, so you stop wondering whether a session is worth doing.
- Flexibility: if life gets in the way, your plan adapts instead of breaking.
- Race focus: training builds toward each race on your calendar, including taper weeks.
- Learning: short videos and explanations help you swim, ride and run better, not just more.
