The Étape du Tour this year was stage 18 from the Tour de France which went from Pau and took in the Tourmalet (17km/7.3%av) and Hautacam (13.6km/7.8av) climbs in the Pyrenees. 148km - not sure what the official elevation is, but my strava says 4,555m - http://app.strava.com/activities/168454353 (my chip time was 7:07)
The conditions were awful!! Heavy rain for most of it, so soaked through by top of Tourmalet.. the temp was 3c at the top so the descent was really hard. Lots of people with hypothermia! It warmed up a bit by the bottom of the Hautacam before the rain again. I read that 13,000 people entered and 4,000 abandoned!
