GNR-GAP index - Go&Race Algorithm Estimate

Based on the elevation profile analysis, running on this course is estimated to result in a pace that is 19.5% slower.

For example, a runner who maintains a pace of 5'00"/km (8'03"/mi) on a flat 20.3 km course, corresponding to a finish time of 1h41'22", is estimated to complete this course in 2h01'10". The recalculated average pace (GAP) improves to 5'59"/km (9'37"/mi), making it 0'59"/km (1'34"/mi) slower.


The following graph illustrates the Pace Adjustment (PA) factor applied to the pace along the course. The horizontal red line represents a PA of 1, meaning no pace adjustment. Above the line, the pace is slower; below the line, it is faster. The table below also provides estimates for other pace ranges.



Predict your race or analyze your performance!

This following table shows simulations for paces between 3 and 8 min/km.

RACE PREDICTION
To estimate a possible race time, use the "Pace" or "Time without slopes" column, which are valid for a flat course.
For example, if you think you can cover this distance on a flat course at a pace of 4'40"/km (or 7'31"/mi), i.e. in a time of 1h34'36", the estimate is to complete this course in 1h53'06", corresponding to a pace of 5'35"/km (or 8'59"/mi).

PERFORMANCE ANALYSIS
If you have run this race, use the table to estimate the equivalent time on a flat course. Check the "GAP" column and find the value closest to your pace, or compare the "Time with slopes" column with your time: on the same row you will find the pace and the equivalent time on a flat course in the "Pace" and "Time without slopes" columns.
For example, a time of 1h49'03" (pace of 5'23"/km or 8'39"/mi) corresponds to a time of 1h31'14" on a flat course (pace of 4'30"/km or 7'15"/mi).

Notes on the calculation of the length, altimetry and slope

Note 1: the length of the route is calculated using the geographic coordinates. This value may differ slightly from the official length declared by the organizers.
Note 2: the altimetry may not correspond exactly to the real values. For routes obtained via Google API, it is possible that the altitude is that of the terrain, without considering tunnels or viaducts. If from GPS tracking, the error is arbitrary.
Note 3: the percentage slope is calculated on sections of at least 50 meters and smoothed. Roads with gradients between -3%% and +3%% are considered flat, between +3%% and +7%% are uphill, and greater than +7%% are considered steep.
