Just one measly second per klm lay between me and a PB at Parkrun this morning!!! Yes -- I ran 5 seconds behind my PB! But how can you possibly know that as your are running!! I did do it a bit tough today - it was quite cold and I don't like that cold air pouring down my gullet into my poor old lungs!! It needs a bit of pre-warming.
Well anyway - I tried - and I only try once per month -- so it's back to long and slow again for a while 15klms run/walk on Monday.
