Metric Trails

CERTIFICATIONS

OLYMPIC CERTIFICATION

Performed by a Certified Measurer using validated GPS devices and advanced elevation models (LiDAR or post-processed GNSS). Offers the highest accuracy and traceability.

COMPETITION CERTIFICATION

The course is measured in the field by a Certified Measurer using an approved GPS device and Metric Trails' standardized procedure. Ensures reproducible and verifiable results.

RECREATIONAL CERTIFICATION

The course is verified in a GIS environment using public topographic data. Metric Trails uses statistical methods and consistency checks.

Research & Publications

Fractal Complexity and Distance Distortion in Trail Running

Trail routes are not smooth lines, terrain complexity alters both distance and elevation gain. We propose a new standard to ensure accurate, reproducible measurements.

Evaluating GPS Devices for Elevation Gain in Mountain Sports

This study compares wrist-worn and handheld devices under real trail conditions, highlighting differences in barometric vs GNSS based gain estimation.

Impact of DEM Resolution on Elevation Gain Estimates in Trail Running

This study explores how digital elevation model (DEM) resolution affects total elevation gain calculations, using real-world trail data and remote sensing tiles.

Gait Transition Dynamics in Uphill Trail Running

Using wearable sensors, we model how trail runners shift from walking to running as slope increases, both in lab and field settings.
