So I went to do week 7 run 3 this morning but never really got into it, I just never felt comfortable and couldn't get into a rhythm. Struggled to about 15 minutes before calling it day. There was just nothing in the tank. Given I've been doing a run every other day for most of the programme I'm confident that it wasn't anything to do with resting between runs but I think it might be down to diet yesterday, we had a family thing and I ate vey little especially in the way of carbs. So I'll be eating better today and trying the run again tomorrow evening.
Kinda trashes my Christmas schedule though as it now puts a run on Christmas Day rather than Christmas Eve and Boxing Day... oh well
