by Markus Rummel. At AI Endurance, your optimized training plan has always been built on data — not guesswork. We start by crunching the numbers: analyzing your recovery, availability, and long-term progression to create an efficient, evidence-based plan.

Now, we’re adding a new layer of personalization: the Plan System Prompt.

This new feature lets you directly tell our LLM-based AI agent how you want your training to evolve — in your own words. After the base plan is generated, you can add a prompt that adjusts your workouts according to your specific goals, preferences, or upcoming events.

The agent has full access to tools that can:

• Move or skip workouts
• Replace sessions with different types
• Create new workouts with any structure you imagine

You can be as creative or as specific as you like. For example:

"Replace some Threshold workouts with Over-Under workouts"

"My race is a mixture of 3-5 min VO2Max efforts with prolonged Endurance and Tempo Efforts. The anticipated duration is 2-2.5 hours. Create a couple of race-simulation workouts in the weeks leading up to my event"

"I want you to half my taper volume"

"For the next month just 2 swim workouts per week, afterwards 3 per week"

"For the next 3 months my bike workouts are on the indoor trainer. Make those bike workouts more interesting and variable"

There are no limits to your imagination. Whatever you can describe, the AI can interpret and implement — intelligently, within your optimized plan.

Try it out today and experience a new level of control over your training.
