Total ascent figure on elevation profile

Richard,

I am on holiday in Slovenia following routes I have ( as usual) planned on cycle.travel. I have completed two routes now and in both cases the total ascents ( as given on the elevation profile) are significantly at odds with my garmin totals ie 70% of the garmin total for one and a v surprising 50% for the other. Obviously, this causes some issues with accurate day planning, although at least they were underestimates. Do you know why this should be?

Regards

John Buswell
