Corsa was built for athletes under 18 from the start — not an adult plan with the numbers turned down. Plans that respect a growing body, language a 12-year-old understands, and parents in charge of under-13 accounts. Running, road cycling, mountain biking and triathlon.
Youth mountain biking gets called out below because almost no other AI coach handles MTB well. But Youth Mode applies to every sport Corsa supports — track and cross-country runners, and young triathletes get the same age-appropriate plans, guardrails, and language.
Mountain biking is the most underserved discipline in AI coaching. Corsa treats it as a first-class sport, with skills sessions, terrain-aware volume, and periodization built around the youth race season.
Young athletes new to training never see a pace target or a heart-rate zone. Every workout says how it should feel instead — “easy enough to hold a conversation”, “breathing too hard to talk”. When an athlete moves up to structured training, the numbers unlock: the same pace and power targets serious juniors race with.
Every workout explains what it builds and why it’s placed where it is. Riders learn while they ride; runners learn while they run. The athlete stops being asked “but why am I doing this?”
Skip a session, swap a day, get sick — tap “Adjust plan” and the plan rebuilds. Athletes pick from common reasons (travel, illness, week changed) and add a note. The plan reflects the change.
For young athletes newer to structured training — our Youth Beginner level — every weekly plan is checked against these limits before your child sees it. The AI writes the plan; our code checks it afterwards and fixes anything that breaks a rule. No setting, and no request from the athlete, turns them off.
Bodies need time to adapt, so training grows gradually.
With 30% less training that week.
During base training.
Juniors who already train in a structured way — our Elite Junior level — get limits built for where they are: at least one rest day a week, no more than 12% more training than the week before, a lighter recovery week after every four weeks of building, and hard efforts capped at 18% of the week in base training. Those are still more conservative than the adult limits on how fast training grows and how much of it is hard.
Two things hold for every athlete at every level. Never two hard days in a row in the same sport. And when an athlete reports two or more sick days, the plan they get back starts easy — no hard session on the first day back.
For athletes aged 7 to 12, the account stays locked until a parent or guardian approves it. Your child types in your email address. Until you approve, we hold only what we need to ask you — your email and your child’s sign-in details — and we delete them after 14 days if you don’t.
You’ll get an email with a plain-language notice explaining exactly what we collect and who receives it. To confirm that a real adult is saying yes, we ask for a one-time $1 card verification — a method the US Federal Trade Commission lists for this purpose. It isn’t refunded and it doesn’t start a subscription.
After you approve, the parent portal lets you:
Your child’s own notes about their workouts stay theirs: the portal shows that they exist, not what they say.
Corsa is designed to meet the requirements of the US Children’s Online Privacy Protection Act (COPPA) and the Texas App Store Accountability Act (SB 2420). This describes how Corsa is designed; it is not a certification, seal or endorsement from any regulator or third-party program.
We show no advertising, and we don’t sell data.
Garmin, Strava and Wahoo can’t be connected. Apple Health on your child’s own device can.
Your child’s name, email and date of birth never reach the AI. It sees a training profile — sports, experience, goals, how sessions went — not who your child is.
Corsa is built to keep young athletes from doing too much too soon. For athletes new to training, the five rules above are applied to every weekly plan; experienced juniors have their own limits, also enforced in code. It isn’t medical advice, and it’s worth checking with your doctor before your child starts any new training programme.
We can, to run the service. Our AI provider receives your child’s training profile to write the plan, never their name, email or date of birth. Stripe processes payments. You can see what we hold, and delete it, from the parent portal. Full details are in our privacy policy.
A one-time card verification that confirms an adult is approving the account. It isn’t refunded and it doesn’t start a subscription.
Yes — pause training or delete the account at any time from the parent portal.
COPPA’s parental-consent rules cover children under 13. If you’ve paused your child’s account, the pause ends on their 13th birthday, and we’ll email you to let you know.
