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:
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.
We explain how AI Endurance uses ChatGPT to help guide your triathlon, running and cycling training.
In this post, we discuss staying motivated executing your cycling training plan when you’re not training for an event. Also we give an update on our training and give a status report on how AI Endurance’s performance predictions are stacking up against reality.
by Stefano Andriolo. Building on previous work, we refine a method to accurately determine the relationship between DFA alpha 1 and power. This method can be used to track fitness and thresholds of an athlete. We find in some cases ramp detection tends to overestimate thresholds, a finding mirrored in recent physiological papers. On the other hand, thresholds based on clustering of DFA alpha 1 values tend to agree well with this new method. We propose a hybrid lab and everyday workout experiment to further study the relationship.
AI Endurance has a built-in race pace predictor for your running and cycling performance. In this post, we discuss how you can use it to predict your pace for your next running race or your goal power for your next cycling event.
