Compare two running blocks across mileage, frequency, long-run distribution, quality sessions, and completion consistency.
Running blocks can change in several dimensions at once. Looking only at mileage can hide simultaneous changes in frequency, long-run share, quality work, or consistency.
The comparator normalizes both blocks into the same fields and calculates long-run share as long-run miles divided by weekly mileage. Differences are shown side by side without an overall score.
Use the output as a transparent planning aid, not as a measurement of fitness or a guarantee of performance. Keep planned workload separate from completed workload, use consistent definitions, and change the inputs whenever the schedule becomes unrealistic.
A long run can become a larger or smaller part of a week even when its absolute distance changes only modestly.
Yes. Use the same numerator and denominator across blocks.
No. It reports what changed.
