Well did Run 1, Day 2, yesterday and tried to run a bit faster on my one minute run sections. Big mistake. Woke up this morning with awful lower back pain. So took one paracetamol and put on some 5% Ibuprofen Gel and 15 minutes later was fine.
So looked up before running stretching exercises and after running stretches and will,be dong them in future and will slow down a bit, well until about week 5, Hee Hee.
Reckon it should work.
