The coaching platform that learns your style
The plan is not the point.
Your athletes are.
The best coaches don't just write programs — they read people. Athlin handles the plans so you can focus on what actually makes you irreplaceable: knowing your athletes, catching problems early, and being there when it matters.
Built for triathlon coaches managing 10–30 athletes. Also works for running, cycling, CrossFit, strength, and personal training.
Sound familiar?
You're spending time on the wrong thing
Sunday night. 15 athletes need plans. You sit in spreadsheets for three hours doing work that feels mechanical — not like coaching.
Meanwhile, one athlete's HRV has been declining for a week. Another skipped three sessions. A third is overtraining before their race. But you haven't had time to notice — you were busy writing intervals.
The athletes who need a conversation are getting a spreadsheet instead.
You became a coach to develop people, not to be a plan factory.
What if instead
Monday morning. Plans done. Time to actually coach.
You open Athlin. AI has drafted personalized plans for every athlete — based on their wearable data, recovery, and your coaching style. You review in minutes. Then you do the part that matters: call the athlete whose sleep has been terrible, message the one who crushed last week, adjust the plan for the one who's struggling.

What makes this different
Your AI, not a generic one.
Every time you adjust a plan, Athlin learns. Move long runs to Sundays? Remembered. Prefer zone 2 for base? Noted. Ease off after poor sleep? Understood. It watches how you coach and becomes better at being you.
After a month, plans need almost no editing. After three months, the AI coaches like you would — if you had unlimited time for every athlete.
Other tools give you a blank calendar or cookie-cutter AI. Athlin gives you YOUR AI — one that coaches the way you do, so you can do the part AI never will: actually care about your athletes.
What you get
Everything that matters. Nothing that doesn't.
See who needs you today
Dashboard shows which athletes need attention right now — poor recovery, missed sessions, overtraining risk. Stop guessing. Start intervening.
Periodization that adapts
Set a race date. Define training blocks. The AI structures the progression and adjusts when life gets in the way — so you don't have to rebuild from scratch.
Did they actually do it?
Garmin activities auto-match against planned workouts. You see who followed the plan and who needs a conversation — without having to ask.
Weekly team briefing
One email every Sunday. All your athletes. Who trained, who didn't, who needs a check-in. The overview that lets you start Monday prepared.
Athletes see their plan instantly
Clean mobile page. No app download. They connect their watch once. When you assign a plan, they get an email and it's right there. That's it.
Garmin & Apple Watch
Activities, HRV, sleep, stress — pushed the moment the watch syncs. Real data, not self-reported. The foundation for plans that actually respond to how your athletes are doing.
Why we're building this
We watched coaches spend 3 hours every Sunday writing plans instead of actually coaching. The athletes who needed a conversation were getting a spreadsheet. The ones showing signs of overtraining were invisible. We built Athlin because we believe the best coaches shouldn't be buried in admin — they should be doing what only humans can do.
Our belief
Coaches matter more than ever.
Everyone says AI will replace coaches. We think the opposite. AI can write a training plan — but it can't look an athlete in the eye and say "I believe you can do this." It can't notice that someone is struggling before they say it. The best coaches do things AI never will. Athlin exists to give them the time to do it.
Frequently asked questions
What trainers ask us
What is a coaching CRM?
A coaching CRM is software that helps sports trainers manage athletes, track performance data from wearables, and generate personalized training plans. Athlin is a coaching CRM with AI that learns each trainer's coaching style over time.
How does AI training plan generation work?
Athlin analyzes each athlete's wearable data (workouts, HRV, sleep), training history, and your coaching preferences to generate personalized plans. Every time you adjust a plan, the AI learns and improves its recommendations.
What sports does Athlin support?
Athlin works with any endurance or strength sport: triathlon, running, cycling, swimming, CrossFit, strength training, and personal training. The periodization system and AI adapt to each sport's specific demands.
How does Athlin learn my coaching style?
Every time you adjust a generated plan, Athlin remembers your preferences. Move long runs to Sunday? Remembered. Prefer zone 2 for base building? Noted. After one month, plans need almost no editing. After three months, the AI coaches like you would.
How is Athlin different from TrainingPeaks?
TrainingPeaks is a training calendar that requires manual plan creation. Athlin is an AI-powered CRM that automatically generates plans that learn your coaching style, monitors athlete recovery, and shows you which athletes need your attention today.
