You run, cycle or swim with your Garmin, and your watch records everything? Heart rate, pace, power, cadence, sleep, HRV? New data is added every day. What if an AI could analyse your endurance training history and create an individual running, cycling or swimming plan with structured workouts that appears on your watch the next day?

This is exactly what the Tredict MCP Server makes possible.

Garmin, Tredict and AI Assistants: A Closed Loop

Tredict is an official Garmin integration partner and synchronises automatically with Garmin Connect via the Garmin Training API. Workouts you complete with your Garmin are automatically uploaded to Tredict. Conversely, structured workouts you plan in Tredict are transferred to your Garmin calendar and loaded onto your watch.

Here is what is new: Using the Tredict MCP Server, AI assistants like Claude, ChatGPT, Mistral Le Chat or Perplexity can access your training data in Tredict, analyse it and plan directly within Tredict. The plan then lands on your Garmin as usual. So, if you like, it is a Garmin MCP server.

Your Garmin records the workouts, Tredict stores and analyses them, the AI creates the plan, and Tredict sends it back to your watch. This means: no export, no manual transfer, no detours.

Tredict officially integrates with Garmin Connect and the AI assistants from Claude, ChatGPT and Perplexity.

What the AI sees in Tredict

The AI does not just receive a simple list like "10 km in 50 minutes" via the Tredict MCP Server. It has access to the full depth of your training data.

On the one hand, these are the second-by-second time series of your activities: heart rate, speed, power, cadence, elevation gain, position. From this, the AI can form its own detailed picture of your training sessions.

On the other hand, it accesses the analysis results that Tredict calculates from this measurement data. The effort values that Tredict redundantly determines from up to three sources (power, heart rate, speed) while considering intensity levels and zone priorities. Your capacity values such as FTP, FTPa, maximum heart rate and lactate threshold, which Tredict automatically detects during suitable intensive sessions. Your individual zone model with sport-specific revisions. The zone distributions over weeks and months. Plus HRV and sleep data, body data such as resting heart rate and weight, as well as your equipment.

This combination of detailed measurement data and calculated analysis values is what sets AI-powered training planning for Garmin via the Tredict MCP Server apart from a simple conversation with an AI about your training.

What you can do with it

Have capacity values determined

You ask the AI: "Look at my intensive training sessions from the last few months and determine my current FTP from them." The AI then retrieves the relevant activities, analyses the power data in detail and gives you an assessment. You can cross-check the result with the automatic FTP detection in Tredict and thus gain a particularly well-founded assessment of your current performance.

Rebuild a recorded training as a workout

Did you have a really good interval session or a tempo run and want to repeat it as a structured workout? The AI can analyse the time series of your completed training and create a structured workout in Garmin with the appropriate target zones. You can save this as a template or have Tredict load it directly onto your Garmin.

Have a training plan created

The AI analyses your training history from the last few months, takes into account your capacity values and your zone model and creates a multi-week training plan directly for your Garmin in Tredict. With structured workouts that use heart rate, pace or power target zones, depending on how you train. The AI usually recognises whether you are training power-based with a power meter or heart rate-based with a chest strap.

The created training plan is reusable in Tredict. This distinguishes it from individual workouts that are simply uploaded somewhere. The plan remains in your training plan library, can be adopted into your training calendar with a start or end date and can also be applied to other athletes. From there, Tredict synchronises the individual workouts automatically to your Garmin watch.

Which AI assistants work?

Any AI assistant that supports the Model Context Protocol (MCP) works with the Tredict MCP Server. Currently, there are ready-made guides for:

• ChatGPT (also with a free account via the official Tredict ChatGPT App in the ChatGPT App catalogue)
• Claude (currently delivers the best results for complex training plans)
• Perplexity
• Mistral Le Chat

If you want to simply try out the Tredict MCP Server, you can do so for free with the official Tredict ChatGPT App. For complex training plans with structured workouts over weeks and months, Claude is recommended as it works with a large context window and delivers the most reliable results for extensive tasks.

Data Sovereignty

You decide whether and which AI provider you connect to Tredict. The Tredict MCP Server only transfers the data that you have released via the permission settings. Unlike unofficial Garmin MCP servers that work with your Garmin access data, Tredict uses the official Garmin Training API. Tredict itself remains fully GDPR-compliant. If data privacy with external AI providers is important to you, take a look at their respective privacy policies or use the European alternative Mistral Le Chat from France. You can find more details in the FAQ on GDPR-compliant account deletion.

An important note

An AI-generated training plan is not a substitute for an experienced coach. If you have never created your own training plans before, you should not adopt an AI-generated plan without checking it. The AI is a tool that can help you, but assessing whether a plan really suits you and your fitness level requires experience.

What has changed, however, is that the data your Garmin collects every day becomes something that actually helps you with your training through Tredict's analysis foundation and the AI. From recording to analysis to the next workout on your watch.
