The cats for climbs are:
4th Category - the lowest category, climbs of 200-500 feet(70-150m).
3rd Category - climbs of 500-1600 feet(150-500m).
2nd Category - climbs of 1600-2700 ft.(500-800m)
1st Category - climbs of 2700-5000ft(800-1500m)
Hors Category - the hardest, climbs of 5000ft+(1500m+)

It's really that simple? I expected grade and length of climb would factor in.
Does the Giro use the same formula (no hors catagorie, of course).

Amazing reading! And why am I not surprised that the French are so inconsistent.
I plotted last year's rated climbs on a graph as to length and grade in order get an idea how the hills around home compare. It was actually pretty successful. e-mail me if you'd like a copy in Excel format. sherwood@telenet.net
Most of the hills I ride fall in the Cat 3 and 4 range. The climbs around me that I would qualify Cat 2s are 6% to 12% with a length of 1.5 to 5 miles. The shorter, the steeper.
All of this interests me, because there is virtually no flat riding near me. I live at the top of a 300', 8% climb no matter which way I ride (not Alpe d'Huez, I agree).
