I was worried about w5r3 and did it first thing this morning so that I wouldn't stress about it through the day.
During the 20 minute jog my mind instructed me to stop many times although my body seemed quite able. I chose not to stop and defeated 'that voice'. It's a really interesting tension between the mind and the body and I hope that in time my mind will choose to send me encouraging messages and not self defeating ones.
On my last 5 minutes a wave came right over my trainers and I jogged on with sodden, leaden trainers and a really big grin. I was so happy and proud of myself.
Wishing all those wk5 runners the very best and I know you can do it!
