How to predict future race paces with your AI

Connect your training data to your AI to see how your current speed scales to different race distances.

Short answer

How can I use AI to predict my race times?

Your AI uses Riegel's formula to calculate how your current speed translates to longer or shorter distances. You provide a recent race time and the target distance, and it handles the math to give you a projected pace. You'll get a clear breakdown of your potential performance.

The results you get

What your AI calculates

Once you provide your recent race data, your AI delivers these specific outputs.

PROJECTION

Predicted race times

The AI calculates estimated finish times for any distance you choose. You get specific time targets based on your current fitness.

PACE

Target split targets

It breaks your projected time down into per-mile or per-kilometer splits. This helps you plan your effort for race day.

ANALYSIS

Endurance gaps

The AI shows how much your speed drops as distance increases. This highlights where you might need more aerobic training.

HUMAN

Training decisions

The AI provides the math, but you decide how to adjust your mileage or intensity based on these numbers.

The workflow

What your AI does when the data arrives.

The AI acts as a specialized calculator that applies endurance modeling to your specific numbers.

  1. Input processing

    Your AI reads the recent race distance and time you provide in the chat. It prepares the data for the calculation.

  2. Formula application

    The agent applies Riegel's formula to your input. It uses the fatigue coefficient to scale your speed across distances.

    estimate_distance_conversion

  3. Distance scaling

    The AI converts your current speed into the target distance you want to race. It handles everything from sprints to marathons.

  4. Output generation

    The AI presents the projected times and paces in a clear format. You can then ask it to compare different target distances.

  • I ran a 5k in 22:30. Use the Training Pace Calculator to predict my marathon time.

  • Based on my 10k time of 45 minutes, what would my 5k pace be if I wanted to race it next week?

  • I just finished a half marathon in 1:45:00. Predict my 5k and 10k times using this data.

  • Calculate my projected 26.2 mile time if my current 10k pace is 8:30 per mile.

FAQ

How the pace predictor behaves

  • 01

    Does the AI know my current fitness level automatically?

    No. The AI only knows the specific race times you provide in your prompt.

  • 02

    Can the AI adjust my training plan for me?

    No. The AI provides the mathematical predictions, but you must decide on your own training changes.

  • 03

    What formula is being used for these predictions?

    The AI uses Riegel's formula to estimate how speed changes over different distances.

  • 04

    Can the AI predict my time for a distance I haven't run?

    Yes. As long as you provide a recent time for a different distance, it can project the new one.

  • 05

    Will the AI change my training logs in my running app?

    No. This MCP only performs calculations; it cannot write to or modify your external fitness apps.
