I normally run in the morning as soon as the kids are packed off to school and my energy levels are still high, but with the half term in full swing its difficult to say the least. This morning children had other plans for me, time disappeared and I thought todays run wouldn't be possible, but as luck had it I managed my run at 3.30pm. Yippee... it felt great to be in that "zone", I was really enjoying it. Then half way through it began to be tough going and my legs felt like lead, I felt exhausted. I pushed myself through it, but the good feeling had been replaced by one of how unfair life can be at times! Its not new, me feeling like this in the afternoon when I run, but I can't work out why? I felt great to start with, no different to how I feel in the morning and I wondered if any of you wise people out there could throw some light on the subject?
