I was just looking for as many hills as I could get in 20 miles. Close to 1000ft / 300m of climbing.
So I rode this route this afternoon:
If you go to the bikemap.net and run your cursor over the route profile a marker runs over the route. It's a lollipop pattern so it's not immediately obvious what the course is.
I'm going to do this once a week for as long as I can through the autumn/winter. I'm checking progress using GarminConnect. No ... it will not be public ;-)
I'll include a more detailed description later.
