I've just done w5r2 and I don't know if it was the soaring music or endorphins finally kicking in after 33 years or just sheer joy, but I burst into tears. I must have looked quite a sight/fright with my red face and red eyes and .... thank goodness I always carry a hankie!
Well, those 8 minutes are okay after all the training we've done. My breathing was very steady, my legs did their own thing and all I had to do was to keep going and slow down endlessly when the going got tough. I was overtaken at one point by a tall sturdy young athlete whose feet didn't look as if they touched the ground. He slowed up and walked ahead of me and it took me quite some time to catch him up and give a little sprint as I overtook him!
Thanks to everyone who has already described how to do this. I remembered someone saying that when you hear you have 4 minutes left you know you've already done 5 so it should be easy! It worked. Keep on blogging everyone, we can do this together.
