Chester 1/2 marathon -hopes dreams

Hi
its Friday night - and not much running this week , just 2 or 3 runs, but last night i did go to the chester 1/2 mara course , and ran 6 miles gently. hoping for a good time sunday , once i get going - my recent best 1/2m is just over 1hr 48, and i think best ever is 1hr 45 over 20 year ago- but the memory plays tricks- i;'d be delighted with 1:47 sunday
happy training
