Update
Tuesday 5km - The achillies was giving me a little trouble Monday and Tuesday whilst sitting at work. I was getting the odd short sharp pain. Anyway come Tuesday night it was feeling OK so I trotted around the block. No dramas with the leg.
Thursday 6km - I didn't get out until well after 10.00pm. Just did a 5km except that I took in a Queens Park/Darley Road extension. No dramas again with the leg, just short of breath at the end. I'll put that down to a strong expresso that I had late in the afternoon.
