Both legs were distinctly tired as I walked into work this morning. I was a little worried that this showed problems from yesterday but during the day I wasn't aware of any problems which is a positive sign.
I ran very gently to the circuit class and there did the squats, lunges and jumps of my strengthening programme in addition to the normal core and upper body work. Walking back home my knees didn't feel painful although both felt 'tired'. I've a few days of rest now before my next run which will be valuable.
