Have been bumbling along fairly well until now - W5 run 1 was OK, I surprised myself by being able to do it first time. However, Run 2 was a disaster (well maybe not a complete disaster, I managed the first 8 minute run), but couldn't do the second - my legs just decided not to co-operate, and were like lead - couldn't run, could just about manage to put one in front of the other to walk home. Anyone else struggled with moving from run 1 to 2 in this week? A horrendous cold arrived the day after, so am wondering if that might have something to do with it? Any advice gratefully received.
