🗒️Monthly Training Trend Calculator

Five weekly figures into a slope

Enter weeks 1 to 5 to get the month total, the weekly average and the least squares trend slope across the weeks. No consistency score or achievement score is produced. Blank weeks are left out of the fit and reported as left out.

The slope is the gradient of the least squares line with the week number on the x axis and that week value on the y axis, so its unit is change per week. A slope of +2.50 mi per week means the fitted line rises by 2.5 miles a week on average. The wording of the trend is decided on the same two decimals shown on screen, so the number and the sentence always agree.

With only one week filled in, no slope can be fitted and only the total and the average are shown. The slope is a line fitted to the points you entered and does not forecast next month. Mixing different training types into one unit also makes the figure hard to read, so keep the unit consistent. Written as of October 2026.

Reading a month as a slope, not a total

A monthly total hides what happened inside the month. The same 75 miles looks very different as 19-19-19-18 than as 10-16-22-27, yet both add up the same. This calculator takes weeks 1 to 5, reports the month total and the weekly average, and at the same time fits a least squares line with the week number on the x axis so you can see how much the figure moved per week on average.

Pick whether you are totalling running distance or strength volume load, and the chosen unit is attached to every result line. Blank weeks are excluded from the average and the fit, and the results list which weeks were left out. Whether the trend reads as rising, falling or flat is decided on the same two decimals shown on screen, so the number and the sentence never disagree. Enter last month total as well and the change against it is reported as a percentage.

This tool produces no consistency or achievement score, because no verified standard defines one. The slope is a line fitted to the points you entered and makes no forecast about next month, and with only one week filled in no slope can be produced at all. Putting distance and volume load into the same field makes the figure meaningless, so keep to a single unit.

FAQ

Why no score?

There is no verified standard that converts consistency or achievement into a score. A score invented here would have nothing to compare against, so the page reports totals, averages and the slope instead.

What does a slope of +2.5 mean?

Fitting a straight line to your weekly values, it rises by 2.5 units a week on average. It is not the gap between two particular weeks but the average change across the whole set.

If I took a week off, should I enter 0?

Enter 0 if that is what happened. Leave a week blank only when you do not know the figure; blank weeks drop out of the fit and the results say which weeks were left out.
