It's the first time I've had to walk before being told to. I just couldn't make it through either of the 10 minute runs in this session. Feels terrible.
I usually go straight out in the morning after nothing but coffee and water but because I'm off work this week I had a fairly light breakfast then went out an hour later. I hope it's this that made the difference but I don't know?
I did about 7 mins of both runs but no way could I do the whole 10. I'll have to retry this session on Friday.
