Week 4 has flown by! Last night was run 3 of week 4 and in 30 degree (celsius) heat I shuffled my way through it. Taking some of the advice that I have seen on here I waited until it was later in the evening, ate a banana before heading out, stuck to the shady side of the street and carried some water with me which really helped during the walking parts.
The last half of the last 5 minutes was tough as I think the heat radiating off my face was competing with the setting sun...but I pushed through and told my brain to shut up with it's constant winging about being tired and wanting to stop. I am impressed with my endurance- the biggest thing I worry about on every run is not being able to catch my breath but it seems that my lungs are doing just fine. I can't believe that I have completed week 4 and can run for 5 minutes straight!
Absolutely terrified for week 5...going to do it anyway :).
