Yes, I have not long got back from completing my second run of week 4 and apart from my lower legs feeling like they have massive weights attached to them towards the end of the final run, all went quite well with no major headaches. I seem to be recovering my breath far quicker than before, I can definitely notice that, and I'm certainly not breaking out into a massive sweat like in the earlier weeks.
I parked on the large ASDA car park in Hayle again, and basically ran up the road parallel with the estuary again until the path ends. Then I turned around, headed back and finished the run off by going all the way around the car park and building itself. Luckily, there is a large pathway all the way around and it's nice and flat.
So, all is good and I feel good...tired, but good!
