I want to do an arrow this year, and reach 100 points (not started yet), and do four essex calendar events for the essex sr (don't want to rely on ece or diy). I need an arrow team!
I can try to work out an easy as possible 500km route if you like.
It'd probably work best as a 9-10am start, head to Kings Lynn area, do a short loop before heading west in the evening and going pretty direct to York via the Trent. With a SW wind, you should get a good tailwind to Kings Lynn area, do the loop while waiting for the wind to drop, then West with a light crosswind and north with a cross-tailwind. It'd have very little climbing too.
The wind might not play ball, but you could always cut the loop out and go for a shorter distance.
