Anyway, I managed to get in just over 1,000 meters over roughly 65 km's by doing the Sandhoogte hill, then coming back down into Greenhaven, then going back up the paved road, past Greenhaven, up to Friemersheim and a few more hills thrown in for good measure. 360 meters of climbing in the 1st hour, and just a fraction under that in the 2nd.
It was hot and dusty - lots of roadworks going on in these back roads today, so plenty of large vehicles tossing up sand and dirt clouds which was a bit oppressive. And I ran out of fluids at km 45 - obviously less than optimal... But all in all a pretty darn fantastic few hours (followed by an afternoon of banana-munching to keep the muscle cramps at bay!).
