Just got back from the etape and a few days watching the tdf afterwards. Hannah's description of the second big climb was absolutely spot on and I have been desperately trying to erase the last 5km of it from my memory ever since but without much success. Stopped, walked, and stopped again during it.
Apart from that it was a fantastic day, weather conditions almost perfect, clouding over nicely on the second climb to keep the temperature down. The descent from the Bargargui was fantastic riding but the 'downhill' section from there to the end involved too many climbs for my liking and a headwind just to finish you off. Finished in 9h18m. The most amazing thing was riding with 8,000 other people on closed roads with so much local support. Not quite the tdf but as close as most mortals will ever get.
Now looking forward to next year.
