Still a while off, but just hit the calendar. The route is the same as previous years, but the start point is different, at Cholsey (which was formerly one of the info controls). Cholsey has a station on the Paddington - Reading - Oxford line, and Didcot is 9k away for faster trains out of Paddington.
The benefit of starting at Cholsey is that final big hill (usually done in the dark) is now just a few k in from the start. It's a nice bit of countryside that I'm sure you will enjoy in the daylight (especially in the first light, if the weather's OK). There will only be two main controls, evenly spaced at 70k intervals, with the Milton control (which was never satisfactory from a controllers point of view) dropped.
