Up till now I've been quietly confident and believed I really was making big improvements with my running.
However I just completed W4R3 and I feel really tired and my legs feel like lead...I was terribly slow on the last 5 minute run. I'm now left feeling quite nervous about my first W5 run on Wednesday and I'm frustrated that my leg muscles still haven't quite caught up with the ambitions of the rest of me.
Any tips for me?
