TT Circuit Assen

Fastest per sector: 2018–2026

Median gap to the fastest rider in each sector within each session, across all seasons at this circuit; active riders only. The name on the layout is the sector leader. Sector split points on the map are approximate.

Elevation change: 3 m (from 10 to 13 m above sea level).

Relief exaggerated 4 times so it can be seen. Elevation from the Copernicus terrain model (5 to 10 m accuracy). On circuits with very sharp crests and dips, such as Portimão, the model smooths the relief and the real elevation change can be much larger. Drag to rotate.

A grid-position track: the grid rules here and it is very hard to come back.

When two teammates disagree between pace and grid, pace wins 67% of the time (between 30% and 90%; 6 cases).

Descriptive, over 8 races (2018–2026). 100 = the track where the grid matters most; 0 = the most open. Within a team, practice pace tells who will finish ahead 7 times in 10, but when the faster teammate qualifies behind, they finish behind 6 times in 10: grid position weighs more than pace.
