Summary stats and stop-overs

I have exported the data behind www.gpscycle.com and you can download it as an Excel file here .

The next task is to decide where the stop-overs will be. I want to do an average of 100 miles a day so that the trip lasts 12 days. However, based on last year's experience, I am going to divide the route by metres ascended rather than by miles.

According to the attached file the total ascent will be around 38,500 metres which is about 3,250 a day. I'm off to do some sums . . .
