Yes, I relate to them all except 1 - although once a long time ago I did 98.5 miles on my bike and went for ride around Detford to make it to a hundred. Having run with Watershed when younger I remember the idea that you underestimate in training to get a positive surprise when racing. I always seemed to be disappointed in both however. Less bothered about measuring nowadays - some recompense for being in my mid-60s I guess.
