Lurking at the back

Another run a bit like Monday - I wasn't slow in the grand scheme of things, but found myself there at the back. We did a pyramid run, 1 to 5 minutes and back again, 1 min rest each time. I was with Claudia, who was getting left further behind than me, so felt we should stick together. I just turned around about 30s before the end of the runs to pick her up again, no problem. We cut the route short, going from North Park to the Avenues via Northfields school instead of the ring road, and finished about the same time as everyone else. 25 minutes of effort seems like quite a lot - on the summer it was more like 16-18.
