Even the most experienced runner will get a bit flustered in the sort of heat we are having in UK at the moment so if you are going through the program give yourself a big pat on the back for sticking with it through the heat and secondly remember that it will be a bit harder in this heat so go easy on yourself if you feel like you are struggling, most runners are right now.
I've just been out and usually on a Sunday I see many runners out and about and it was sparse viewing today, so either they went out really early or the heat was just too much.
Here is a link to a really good BBC program about how to spot heat exhaustion.

Take good care of yourselves and run safe.
