Completed week 4 today. The first two times I completed the runs it was ok. In fact I found that the second half of the run easier than the first. Think that's because I have to run slightly uphill for the first half with the return therefore being downhill. Tonight was hard work. My legs felt like lead and I'm sure Laura tells fibs when she says 1 minute to go! Anyway I managed to carry on and complete it so quite pleased with myself.
Now I have week 5 on the horizon - that's my Friday evening challenge!
