Since getting new shoes at the end of June I've been running PBs all over the place. Still not fast in comparison to most of you lot, but seeing sudden, big improvements. Having shaved about 40 secs of my 5k PB over the last 10 days I went out again today and my pixie dust shoes worked their magic again. I knocked over 50 secs off again and came in at 32:34! That is a big jump. I suppose the pixie dust will wear off soon and the gremlins will wake up, but I'll enjoy it while it lasts. Ultimate goal is the elusive 30 mins, but I don't know if that's realistic for these old bones.
