Sandras Ultra Trail
Unifies course verification, checkpoint closing windows, and medical clearance state machines across five mountain race categories (70K, 50K, 24K, 10K, 5K) on Mount Sandras.
APPLICATION / RESEARCH DOSSIER
Working context
Multipath GNSS jumps inside steep canyons and pine canopy inflated cumulative climb and skewed intermediate aid-station cutoffs, while tracking medical certificates and mandatory mountain gear across spreadsheets created race-morning bottlenecks.
Per SPEC-03, Haversine distance integration and DEM/gradient filters quarantine anomalous points as `SUSPECT` without deleting raw traces. Station windows lock to `km + D+/100` KM-Effort, and start-list confirmation requires `VERIFIED` medical clearance.
Weather reroutes recalculate every station window deterministically in seconds with zero formula drift; available for scoped pilot deployments with endurance organizers.
