Cycling 45:00 [1] 14.0 km (18.7 kph)
Rode down to Dalkeith to check the metro course. Stopped to check the opening hours of the patisserie near the start (8am-4pm) and realised my front tyre was getting very soft. I pumped it up just before starting and didn't have any spares, tools or pump so decided I'd better head for home. Made it home safely by going very carefully around all the corners. Found the valve had nearly ripped off, possibly related to bending it when going through a ditch with the bike on the back of the car a few years ago.
