This is the end of the Castlelaw climb from the south side. It's definitely longer than the climb from the north but at least the surface is rideable. Tonight we set off at about 5.30 pm and did the Castlelaw climb first, then along to the rough track round Black Hill to meet the track that comes up from Flotterstone. We then doubled back up to the top of the track to Balerno, rode part of the way down to then cut along to Harelaw reservoir, from there it was back up the track over to Glencorse reservoir, down to Flotterstone, up the road and turned left to descend through Mauricewood down to Auchindinnie. From there it was back along the railway track towards Rosewell with the added challenge of what I call Dougie's Double Challenge, a rough little section of track and a couple of tricky roots to get over, one going uphill and the other within five yards going downhill. For the first time I managed to clean them both tonight, I usually get the handlebars caught in the fence that runs alongside them. My total mileage for the day which included a cycle ride in the afternoon (which was a bit easier) was 48.5 miles, most of which was offroad.
