Tested against recorded finishes
More checkpoints. Less guesswork.
Historical evaluation is loading.
Each runner is excluded from their own reference data. This tests the same completed 2025 event; it does not establish accuracy for a future edition or predict whether a runner will finish.
Precision with perspective.
Predictions are rounded to minutes. Recorded splits keep their exact seconds; exports retain the underlying forecast values.
A historical snapshot.
This is a replay of Ecotrail Madeira 2025, not a live timing feed. Forecasts use completed trajectories from the same event.
