And the best thing about surgical gloves is that you can go up to your mate, stretch the fingers out and let them snap back, and say "now this won't hurt but you won't like it much".
Matt, looks like I will be heading in your direction on the same day as the Reading half, to do the Fleet. Although I live in Reading, I only do the race here if there's nothing else on the day. Too crowded. Fleet is great.
You've shown you can do it, now you need to consolidate while you're waiting to do it again. You don't say your age but I'm guessing it's 1.5 miles in 11 mins something, yes? About 7 mins 30 seconds to the mile. Muttley Jnr did it a short while back to join the RN.
Find time to do three or four runs a week. Do them at an easy, comfortable pace, half an hour or so, no need to go further. If in doubt, go slower.
But use one of the runs each week to sharpen up. In the first week, warm up and try doing 4-6 x 400 metres at hard but sustainable pace with a couple of minutes rest in between. Second week, 2-3 x 800 metres with 3 minutes in between. The third week, try a mile at that pace. If you haven't got a GPS to measure distance, go by time - 90-100 seconds, 3 and a half minutes, 6 and a half minutes, or thereabouts. Take a rest day after doing these.
