Agree this is sound thinking. I'd come to pretty much the same conclusion on those days when you are pedalling along thinking how you'd do it.
Kurt's strategy of banging out consistent miles over 365 days is entirely sensible. I think this is possible in the States, where you can flit between states with (broadly) consistent weather conditions.
Whether it is possible in the UK, with shorter days and colder weather in winter, remains to be seen. Personally I suspect it means that UK riders would need to do more miles in the summer and less in the winter, but not to the same extremes as were being scheduled by Steve at the start of the year. I also suspect it needs some opportunistic riding, particularly in the winter, to take advantage of breaks in conditions as an offset against those occasions when the weather isn't playing ball.
I think Miles is making a fundamental mistake seeking to mirror Tommy's progression. Come 6 months, he is going to struggle to keep pace and will fall behind. He will then be left seeking to do more in the last 3 months of the year than Tommy did. Will be interesting to see the progress on Jo's fabulous charts.
