THE CLIMBS .........
Col de Aspin:-
Length = 13Km from Arreau to the top.
Climb = 800 meters
Average gradient = 6.2%
Steepest Km = 9.5% (Km 7 to 8).
Col de Tourmalet:-
Length = 18Km
Climb = 1256 meters
Average gradient = 7%
Steepest 5Km = 10.2% (Km 8.3 @ Pont St Ardour - Pont Mongie)
Steepest gradient = 14%
First 400 meters of descent = 15%! (take care!)
Climb to Luz Ardiden:-
Length = 11Km
Climb = 1035 meters
Average gradient = 9.4%. It is probably quite well graded - there are lots of hairpins! No data on the steepest bit but it looks about 10% from the map.
So take it steady - and I hope to see you at the finish!! (if I get there!)
