Green Pull Request Won’t Merge: Why It Stays Blocked

A green pull request (all checks passing) can still stay blocked when branch protection rules require a review, a clean mergeable state, or a specific base branch that hasn’t been met. The most common cause is a missing approval from a required reviewer, but stale branches, merge conflicts, or pending status checks that aren’t visible in the main list also hold it back. This article explains every reason a green PR stays blocked and how to unblock it.

Formula

The calculator works out your average pace and speed for a run, ride, or walk. You enter the finish time (in minutes) and the distance (in kilometers). The pace is the time divided by the distance, giving you minutes per kilometer. The speed is the distance divided by the time in hours, giving you kilometers per hour.

Pace = t / d

Speed = d / (t / 60)

Where:

• t = finish time in minutes
• d = distance in kilometers

Worked Example

Using the default values from the calculator (50 minutes, 10 km):

1. Pace = 50 / 10 = 5.00 min/km
2. Speed = 10 / (50 / 60) = 10 / 0.8333 = 12.00 km/h

The calculator shows a pace of 5.00 min/km and a speed of 12.00 km/h.

When to Use This Pace Calculator

Use this tool when you want to know your average pace for a training run, a race, or a commute. It helps you set realistic goals, compare different workouts, and plan your pacing strategy. For example, if you want to run a 10 km race in under 50 minutes, you need an average pace faster than 5.00 min/km.

How to Read the Results

The pace result tells you how many minutes it takes to cover one kilometer. A lower pace is faster. The speed result tells you how many kilometers you cover in one hour. A higher speed is faster. Both are useful depending on whether you think in minutes per kilometer or kilometers per hour.

Common Mistakes

• Mixing units: If you enter distance in miles, the result will be in minutes per mile, not minutes per kilometer. Convert miles to kilometers (multiply by 1.60934) before entering.
• Using seconds: If you enter time in seconds, the pace will be seconds per kilometer, which is not standard. Always convert to minutes.
• Rounding too early: Rounding the pace to one decimal place is fine, but don’t round intermediate steps in the speed calculation, or you may get a slightly different result.

Limitations of the Formula

This formula assumes a constant pace throughout the activity. Real-world runs have hills, stops, and changes in effort, so the average pace is just that – an average. It does not account for elevation gain, wind, or surface type. For training purposes, it’s a good baseline, but it doesn’t tell you about your heart rate or perceived effort.

Frequently Asked Questions

What is a good running pace for a beginner?

A beginner might run at a pace of 7:00 to 9:00 min/km (11.2 to 8.6 km/h). This varies widely by age, fitness, and gender. The best pace is one that lets you hold a conversation while running.

How do I convert pace from min/km to min/mile?

Multiply the pace in min/km by 1.60934 to get min/mile. For example, 5.00 min/km × 1.60934 = 8.05 min/mile.

Can I use this for walking?

Yes, the same formula works for walking. A typical walking pace is around 12 min/km (5 km/h), but it depends on your stride and fitness.

Why does my GPS watch show a different pace?

GPS watches often show current pace, which fluctuates with your speed at that moment. This calculator gives you the average pace over the whole distance, which is more stable.

Does elevation gain affect pace?

Yes, climbing hills will slow you down. This calculator does not account for elevation. For hilly routes, your average pace will be slower than on flat ground for the same effort.
