just got back from thismornings run. it wasn't good. I had to stop to walk 5 times for a minute or 2. wast out of breath body felt fineisn I just couldn't go on. been fine on every run so far even wk5 r3 I felt I could have gone on for another 20 mins. just done blood pressure and temperature and they seem ok. feeling quite uneasy on my feet now though and not feeling quite right. has anyone else had anything like this? think i need to do this run again.
