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 0.4% slower.


For example, a runner who maintains a pace of 5'00"/km (8'03"/mi) on a flat 42.2 km course, corresponding to a finish time of 3h30'58", is estimated to complete this course in 3h31'49". The recalculated average pace (GAP) improves to 5'01"/km (8'05"/mi), making it 0'01"/km (0'02"/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.

This following table shows simulations for paces between 3 and 8'/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 3h16'54", the estimate is to complete this course in 3h17'41", corresponding to a pace of 4'41"/km (or 7'32"/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 3h10'38" (pace of 4'31"/km or 7'16"/mi) corresponds to a time of 3h09'52" on a flat course (pace of 4'30"/km or 7'15"/mi).

Notes on the calculation of the length of the route, on the altimetry and on the slope

Note 1: the length of the route is calculated using the geographic coordinates of the points that compose it, thanks to a specific formula. This value may differ slightly from the official length declared by the organizers of the race, which is valid in case of discrepancies.
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 the presence of any tunnels or viaducts. If, however, the route was obtained from GPS tracking (for example with sports watches), the error is arbitrary and may depend both on the GPS coverage at the time it was recorded and on the performance of the device used.
Note 3: the percentage slope is found by calculating considering sections of at least 50 meters and is subsequently subjected to a "smoothing" process to reduce the possibility of artifacts and obtain a more realistic trend. For classification purposes, roads with gradients between -3% and +3% are considered flat, those with gradients between +3% and +7% are uphill, and those with gradients greater than +7% are considered steep. The same classification applies to descents. This classification is to be considered arbitrary and is a choice of goandrace.com.
