Can anyone help explain, I'm looking at he Strava times for the alpe d'huez climb and in the over 55s section the vam figures don't seem to tally with the metres ascended that are on the internet covering the description of the climb, in particular after the first top 50 places they appear to be less than the start and tourist finish. Should not the metres ascended all match or am I reading it all wrong ? Basically I'm trying to work out what a good times for that climb would be age 60
