All updated. That was hilly. 2,179m (according to RidewithGPS - my preferred method) Started out into a very brisk headwind, turned around half way and before I could really start to appreciate the tailwind I hit the hills. I did a new (to me) hill - the B2026 from the South into Ashdown Forest. Probably the nearest thing to an alpine pass in this neck of the woods - over 6km of continuous climb. Not terribly steep, generally about 4%, but it went on ... and on ... and on.
My Garmin Oregon died, which just goes to show that Modern Things are Rubbish. Fortunately I had a steam-powered old fashioned Garmin 60 CSx in my saddlebag to carry on recording.
Edit: Before you antigarministas jump on this. The Oregon didn't die. The batteries ran out and I replaced the dead batteries with some more duds.
