# Running Split Calculator AI Agent Connect

> Running Split Calculator is a precision utility for runners. It handles all the math for your training, from calculating specific segment durations to generating full pacing schedules. Instead of manual math, your AI client calculates the exact speed you need to hit your target finish times or compares performance between different segments of a run.

## Description

You shouldn't have to pull out a calculator mid-workout or spend time on spreadsheets to plan a race. This MCP handles the heavy lifting for your training math. Whether you are trying to figure out if you are hitting your splits during a long run or you need to know exactly what pace to hold to finish a marathon in a specific time, your agent does it instantly. You can use it to build a complete pacing strategy for a specific distance or just check how much faster one segment was compared to another. It turns your AI client into a specialized running coach that understands the relationship between distance, time, and pace.

## Tools

### get_cumulative_splits
This tool builds a full pacing schedule. It generates a list of elapsed times for every interval at a specific distance mark based on a constant pace.

### get_pace_from_time
This tool calculates required speed. It determines the exact pace you need to cover a specific distance within your target total time.

### get_segment_split
This tool finds the duration of a single segment. It calculates the time required to finish one specific distance at a given pace.

### get_split_difference
This tool compares performance. It calculates the time difference between two different segments or two different paces over the same distance.

## Prompt Examples

**Prompt:** 
```
How long will it take to run 5km at a pace of 5 minutes and 30 seconds?
```

**Response:** 
```
It will take 27:30 to complete 5km at that pace.
```

**Prompt:** 
```
What pace do I need to run 10km in exactly 50 minutes?
```

**Response:** 
```
To finish 10km in 50 minutes, you need a pace of 5:00 per km.
```

**Prompt:** 
```
What is the time difference between running 1km at 4:00 pace and 4:15 pace?
```

**Response:** 
```
The difference is 00:15.
```

## Capabilities

### Pacing Schedules
Your agent generates lists of elapsed times for every interval of a run.

### Target Speed Calculation
Your agent determines the exact pace needed to hit a specific finish time.

### Segment Analysis
Your agent calculates the time for individual distance chunks.

### Performance Comparison
Your agent finds the time difference between two different paces or segments.

## Use Cases

### Race Day Planning
Ask your agent for the exact pace needed to hit a specific marathon goal time.

### Interval Training
Generate a full list of cumulative times for a series of repeated distance segments.

### Performance Tracking
Compare the time difference between two different segments of a long run.

### Segment Timing
Calculate how long a specific 1km or 5km stretch will take at a set pace.

## Benefits

- Eliminates manual pace calculations during training planning.
- Provides exact elapsed times for every interval in a run.
- Converts target finish times into actionable pace targets.
- Compares segment differences to track pacing consistency.

## How It Works

Connect the MCP to your AI client and start asking for pace math.

1. Connect your preferred client like Claude or Cursor to Vinkius.
2. Type a request about your running goals or distances.
3. The agent uses the specific tool to perform the math.
4. Receive the exact times, paces, or differences instantly.

## Frequently Asked Questions

**How do I use this with Claude?**
You connect to Vinkius once, and the Running Split Calculator MCP becomes available as a tool within your Claude interface.

**Can I use this to plan a full marathon?**
Yes, you can use the tool to determine the pace required for any distance and generate cumulative splits for the entire race.

**Does this work with my existing running apps?**
This MCP works with any MCP-compatible client like Cursor, Windsurf, or VS Code, rather than directly syncing with fitness hardware.

**What kind of math does this handle?**
It handles pace-to-time conversions, time-to-pace conversions, cumulative split generation, and segment time differences.

**Do I need to host this myself?**
No, Vinkius hosts and manages the MCP so it is ready to use immediately after you connect.

**How do I calculate my total time for a run?**
You can use `get_cumulative_splits` to see the total elapsed time at various distance marks based on your target pace.

**Can I compare two different paces?**
Yes, use `get_split_difference` to find the exact time difference between two different paces over the same distance.

**How do I find the pace needed for a specific goal time?**
Use `get_pace_from_time` by providing your target distance and the total time you want to achieve.
