Explain how amateur masters racers average speed has increased so clearly.
First off, 2005 and before - 147km. 2006 and after - 138km.
--The chart, all gains from 2000-2006 don't matter, course changed.--
Looking at the pro or elite category for that race - much different story.
2006 winning time - 4:23
2025 winning time - 4:25
-With all the years in between being in that same range +/-
So the pro riders saw little or no performance gains over a 20 year period.
Disc brakes, electronic shifting, 12 speed... they really do nothing for speed. Aero gains help a little on a course like this - but nothing stands out as obvious.
I imagine the increase in masters speed is due to having better masters in the race.
