Lactate Training is not a blood-testing service. It uses the heart-rate, pace, power and training data you already collect to help estimate training zones, understand your sessions and plan smarter around everyday life. No blood test needed.
Included in Basic, Pro and Max
💬 Unlimited WhatsApp coaching
Message your AI coach as often as you need. Ask about training, share feedback, check in and request calendar changes. WhatsApp coaching messages do not use your in-app AI question or report allowance.
Other actions, such as sending workouts to Garmin, still follow your plan’s individual usage limits.
Included with Basic, Pro and Max
🤖 More than read-only: plan and edit your training with Claude or ChatGPT.
Connect your Lactate Training account to Claude or ChatGPT and take action right from the conversation. Review your activities and available Garmin health data, then change your training without hopping between screens.
- Plan ahead: create, move and edit upcoming sessions and training plans
- Update your training data: correct sessions and keep your calendar accurate
- Personalise your coach: edit your questionnaires, goals, coaching memory and coaching style
- Send workouts to Garmin: use supported watch-delivery actions within your plan allowance
Choose an edit-access link to make changes; a read-only link can only view data. Review any changes you request. Requires a paid Lactate Training plan and a compatible external Claude or ChatGPT account; external AI subscription is not included and this integration is excluded from the free trial.

Your training, in more places
🤖 Claude & ChatGPT
Read, edit and plan ahead directly in Claude or ChatGPT. See sessions and available Garmin health information, create or move upcoming workouts, update training data, and edit your questionnaires, coaching memory, preferences and coaching style. You need an edit-access link to make changes; a read-only link only lets the AI view data. Requires a compatible external Claude or ChatGPT account, which is not included with Lactate Training. This paid-plan integration is not available during the free trial.
💬 WhatsApp coaching
Basic, Pro and Max include unlimited WhatsApp coaching. Ask questions, share session feedback, check in and request calendar changes without a monthly WhatsApp message cap. WhatsApp coaching messages do not count towards your in-app AI question/report allowance. Separate limits still apply to actions such as Garmin workout sends.
Good to know
Is the 30-day trial really free? Will I be charged?
Yes, it's completely free for eligible new athletes. You receive 30 days of Pro-level app features without providing payment details. There is no automatic paid subscription or charge at the end. Choose Basic for £4.99/month, another paid plan, or stay on Free. The external Claude/ChatGPT integration is only available on a paid plan and is not included in the trial.
My session analysis showed an error. Will I lose a report allowance?
No. A failed analysis does not count towards your AI report allowance. If you see an error, hit Refresh, then report the issue so we can investigate. A successfully completed new analysis uses its usual allowance. Read troubleshooting advice.
Can Claude or ChatGPT actually change my training?
Yes. With an edit-access link you can ask your external AI to create or change future sessions, update training information, questionnaires, coaching memory and coaching style using supported actions. A read-only link can see data but cannot edit. Always review changes in your app. Included on Basic, Pro and Max; an external AI account is needed and the integration is excluded from the free trial. See setup guide.
Is WhatsApp coaching really unlimited?
Yes. Basic, Pro and Max include unlimited WhatsApp coaching messages. You can chat with your AI coach without a monthly WhatsApp message cap. Separate allowances apply to in-app AI questions/reports, plan builds and Garmin workout sends.
What happens when my 30 free days end?
No card is needed to start the trial, so you won't be automatically charged for a paid plan. Afterward, choose Basic for £4.99/month, upgrade to Pro or Max if you need higher AI limits, or remain on Free.
How does the 30-day trial work?
Eligible new accounts get 30 days of Pro-level app features and allowances, without payment details. Afterward, select a paid plan or stay on Free. The external Claude/ChatGPT connection requires a paid plan and is excluded from the trial.
Do I need Pro for the dashboard, comparisons or weather?
No. These are also included on Basic. The main difference between Basic, Pro and Max is the usage allowance.
Can I connect Garmin and Strava on Free?
Connection availability depends on your app access. Currently, making a new Garmin or Strava connection in Settings requires an active trial or paid plan. Don't assume a new Free account can connect without a trial.
Are all sessions automatically given a full AI report?
No. Automatic names and short summaries are different from full AI analysis reports, which use the monthly report allowance.
How do I check my allowance or subscribe?
Open Settings → Usage & Limits to check remaining usage, or Settings → Manage subscription to see local App Store/Google Play prices. UK prices above are indicative and your app store shows the price for your region.
How do I cancel or request a refund?
Manage or cancel a paid plan through Apple or Google subscriptions. Deleting the app does not cancel it. For refunds, visit the store's official refund process or contact Barney directly at barney@lactatetraining.ai. Read cancellation, refund and contact instructions →
