I read other peoples comments about W6R1 and how it can catch you out - so I approached it with caution and I'm glad I did.
The first five minutes were OK, second 8 minutes and I was starting to feel Tuesdays 20 minute run and by the time I started the last 5 minutes run I was seriously hurting - legs like lead, shins, knees and ankles all letting me know they were there....
I finished about 100yds shy of my starting point so kept running till I reached it but I was struggling.
For the first time I didn't enjoy my run and doubted my ability to stay on schedule but this morning I feel OK and am already thinking about W6R2 tomorrow.
This running thing is additive!
So if you're reading this on the euphoria of completing W5R3, don't panic, but pace yourself and be prepared for a potential hiccup. Get through this and I reckon the end is in sight!
