# Training Pace Calculator MCP > Training Pace Calculator MCP. It calculates your running zones and predicts race times. Give it a 5K time or your VO2max, and it tells you exactly how fast to run for your easy days, tempo runs, and intervals. It even uses Riegel's formula to show you how your pace will drop when you move from a 5K to a full marathon. ## Overview - **Category:** productivity - **Price:** Free - **Tags:** running, training, pace, fitness-tracking, marathon ## Description The Training Pace Calculator MCP takes the guesswork out of your training plan. If you're tired of guessing whether your easy run is actually easy enough, this tool does the math for you. You just tell your agent your recent race results or your physiological stats, and it builds out a specific plan with targets for every intensity level. It handles the conversion between miles and kilometers automatically, so you don't have to do mental math while you're trying to focus on your form. When you're planning for a big goal like a marathon, it uses proven formulas to project how your pace will shift as the distance increases. It's one of the many tools you can access through the Vinkius catalog to make sure your training actually aligns with your goals. Instead of scrolling through spreadsheets or trying to remember old formulas, you just get the numbers you need to hit your next PR. Most runners struggle with the transition from short distance speed to long distance endurance. This MCP bridges that gap by providing clear, actionable targets for every stage of your progression. Whether you're a beginner looking for your first 5K or an elite runner eyeing a sub-three-hour marathon, having precise numbers for your aerobic, tempo, and interval sessions keeps you from overtraining or underperforming. You get a clear roadmap that adapts to your current fitness, making it easier to stay consistent and see real progress without the headache of manual calculations. ## Tools ### estimate_distance_conversion Predicts your pace for a new distance based on a current performance using Riegel's formula. ### calculate_zones_from_pace Turns a recent race result into specific training zones for both miles and kilometers. ### calculate_zones_from_vo2max Estimates your training zones based on your physiological VO2max value. ## Prompt Examples **Prompt:** ``` Calculate my training zones based on a 5K pace of 05:00. ``` **Response:** ``` Based on your 5K pace of 05:00, your training zones are: Easy (05:45 min/km), Aerobic (05:25 min/km), Tempo (05:10 min/km), Interval (04:55 min/km), and VO2max (04:45 min/km). ``` **Prompt:** ``` What is my predicted 10K pace if my current 5K pace is 04:30? ``` **Response:** ``` Your predicted 10K pace is approximately 04:52. ``` **Prompt:** ``` Calculate training zones using a VO2max of 45. ``` **Response:** ``` With a VO2max of 45 ml/kg/min, your estimated training zones are: Easy (06:10 min/km), Aerobic (05:50 min/km), Tempo (05:35 min/km), Interval (05:20 min/km), and VO2max (05:05 min/km). ``` ## Capabilities ### Get training zones from a recent race pace Turn a 5K or 10K time into specific targets for every intensity level. ### Calculate intensity levels from a VO2max score Set your training zones based on your physiological capacity. ### Predict pace changes for different race distances See how your pace will shift as you move from shorter to longer goals. ### Convert targets between miles and kilometers Get your training numbers in both imperial and metric formats automatically. ### Map out specific interval targets Get precise speed requirements for your hardest workout sessions. ## Use Cases ### Planning a 5K to Marathon jump A runner wants to know what their marathon pace will be. They ask their agent to predict the pace change based on their 5K time. ### Setting up a weekly plan A runner has a 10K time and wants to know their easy day pace. They ask their agent to calculate their zones from that pace. ### Starting a new program with no recent races A runner knows their VO2max is 45. They ask their agent to set their zones based on that score. ### Switching units A runner who usually trains in miles needs to see their targets in kilometers. The MCP provides both formats automatically. ## Benefits - Stop guessing your training intensity. Get exact targets for every type of run by calculating your zones from a recent race pace. - Plan for your biggest goals with confidence. Use the distance conversion tool to see how your pace will shift as you go longer. - Get personalized targets from your biology. Use the VO2max tool to set zones based on your actual physiological stats rather than just a recent race. - Save time on manual math. The MCP handles the conversion between miles and kilometers for every zone it generates. - Build a smarter training block. You can quickly generate a full week of varied workouts with specific targets for every session. ## How It Works The bottom line is you get a specific training plan without doing any math. 1. Tell your agent your recent race time or your VO2max score. 2. The MCP processes the data using Riegel's formula or standard fitness models. 3. You get a breakdown of your Easy, Aerobic, Tempo, Interval, and VO2max zones. ## Frequently Asked Questions **How does the Training Pace Calculator MCP use Riegel's formula?** It uses the formula to predict how your pace changes as you increase your race distance. **Can the Training Pace Calculator MCP convert miles to kilometers?** Yes, it provides all calculated zones in both formats automatically. **What zones does the Training Pace Calculator MCP provide?** It gives you Easy, Aerobic, Tempo, Interval, and VO2max zones. **Can I use the Training Pace Calculator MCP if I don't have a recent race time?** Yes, you can generate zones based on your VO2max score instead. **Is the Training Pace Calculator MCP good for marathon planning?** Yes, it's specifically designed to help you predict pace shifts for longer distances. **Does the Training Pace Calculator MCP work with Cursor or Windsurf?** Yes, it works with any MCP-compatible client. You can plug it into Claude, Cursor, Windsurf, or VS Code to get your pace data where you work. **Does the Training Pace Calculator MCP store my personal fitness data?** No, it doesn't save your info. The MCP processes your VO2max or race times locally within your session and doesn't keep a history of your data. **How do I connect the Training Pace Calculator MCP to my AI client?** You connect it through the Vinkius dashboard. Once you've linked it, your agent can use the tools to calculate your zones or predict your future pace.
