#1 realising while pounding along with the Can-Can playing in the headphones that you're actually conducting it, to the great amusement of passing motorists. (Good running music though!)
#2 realising, not much later, that you're doing it AGAIN, this time to Johnny Got A Boom-Boom (ditto)
#3 not looking where you're going and running into a hedge. Ah well, at least it wasn't a hawthorn hedge.
But I did manage 6.73 Km in 42 mins 19secs. Map my Run tells me that is 9.5Km/hr and my trusty calculator tells me that equates to 63 mins for 10K. Really pleased about that because without consciously 'training' for 10K, just going out and doing slightly longer runs, I'm on the pace and only 3K short. Yay!!!!!! [Thinks back in amazement to starting C25K in January and running 1 min at a time; this programme is incredible]
