It was a rare sunny day in London today.  I still wore my long pants and double layers, but got a bit overheated so I took my gloves off.  I warmed up by walking around the dock area and doing a little jogging.  I took a slow pace throughout the whole run.  My legs felt a bit leaden and heavy and a bit restricted by the long pants.  It felt like a hard run, but got better towards the end.  This seems typical for my long runs: it really takes me about an hour to get into these.
