Your own plan will look different.
The app builds yours from your race date, your week and your thresholds, and sends each session to your Apple Watch.


When your week doesn't go to plan.
- A short night or a low HRVThe hard session becomes an easy one and moves later.
- A missed sessionKey sessions move. Easy ones are dropped.
- Sick, injured or travelingkovaa rebuilds the next few days, then eases you back in.
- You get fasterkovaa suggests new targets after a test or race.
Questions
How many weeks do I need to train for a Sprint triathlon?
kovaa builds a 12-week plan for a Sprint triathlon if you have that long. With fewer weeks, it keeps the taper, cuts the base phase the most, and trims build and peak to fit. A full race plan needs at least 8 weeks for beginners, 6 for intermediate and 4 for advanced athletes. With less time than that, kovaa gives you a plan to finish safely instead.
How many hours a week does Sprint training take?
Beginner: about 3–6 hours a week. Intermediate: about 5–8 hours a week. Advanced: about 6–8 hours a week. Every third or fourth week is a lighter recovery week. Short on time? The intermediate plan also fits into 5–7 hours.
What happens if I miss a session?
kovaa rebuilds the rest of the week. Key sessions get moved, easier ones get dropped, it won't stack two sessions on one day, and the week's load stays within safe limits. Small changes happen on their own. Bigger ones show up as a suggestion you can accept or skip.
Is this the plan I would get in the app?
Yes, it's the same engine. Yours is built around your race date, the days and hours you have, your thresholds (FTP, threshold pace and CSS) and any injuries, then adjusted every morning from your sleep, HRV and resting heart rate.
