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:
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 get it, virtual races are not the same as actual races in terms of staying motivated. That's why AI Endurance is introducing a new maintenance running schedule to keep you in shape during the pandemic.

Apple Watch has been a popular choice in running and triathlon. You can now track and execute your AI Endurance custom running, cycling and swimming workouts on your Apple Watch.

Paris to Ancaster is the biggest gravel grinder bike race in Canada. It’s in 8 weeks and I need to get in shape. AI Endurance can predict race performance and create a training plan which is optimized to my training responses. It predicts that I can increase my FTP by 14% to 293 Watts on race day with just 3.5 hours of training a week.

In this post, we explain how to use AI Endurance’s cycling training plan that we generated for Paris to Ancaster, Canada’s biggest gravel racing event. The plan includes detailed workout instructions. For indoor cycling, we show how to use AI Endurance with Trainerroad and Zwift.
