01 / The standard

Built like a lab.
Made for real life.

Most training apps are a black box. Aerobe links every rule in your plan to the research behind it, grades how strong that research is, and says so when the evidence is thin.

You get the decision and the reason, in plain English.

A rule in every planInjury prevention
Long runs

No single run jumps more than 10% past your recent longest.

In 5,205 runners followed for 18 months, one big jump in a single run was linked to more overuse injuries. A big week was not.

Morning, Alex. Ask me anything about your training. I'll answer from your data and show you the research.
03 / The AI coach

A coach that
shows its work.

Most AI chat sounds confident and cites nothing. Aerobe's coach answers from your own numbers and the graded research, and tells you when something is beyond it.

  • Knows your trainingYour check-ins, watch data, plan, races and history.
  • Cites the research, gradedEvery answer points to its source and how strong it is.
  • Knows its limitsNever invents numbers, and sends you to a doctor when it should.

07 / The details

Good questions.
Clear answers.

We're building Aerobe now. Here's what to know.

What is Aerobe?

An AI endurance coach for half marathons, marathons, ultras, triathlons and HYROX. It builds your plan from graded research, adapts it daily and explains every decision.

Do I need a coach to use it?

No. Aerobe is built to be your whole training system. If you already have a coach, it works alongside them.

How is the AI coach different from a general AI chatbot?

It answers from your own training data and Aerobe's graded research library, cites its sources, never invents numbers, and tells you when to see a doctor or physio.

Will it work with my watch?

Garmin, Apple Watch, COROS, Polar, Suunto, Wahoo, WHOOP and Oura are on the roadmap, along with Google, Apple and Outlook calendars. Connections aren't live yet and depend on each company's approval.

Is this medical advice?

No. Aerobe is training guidance, not a medical device. It watches for warning signs and tells you when to see a doctor.

When does it launch?

No date yet. People on the early access list get in first and hear news before anyone else.

20-second check
