As there was a little conversation this morning about my hope to cycle to work, I thought I would provide an update on today's activity. I had things to do today so the route changed. In conversation earlier I had been told of a website that will find the flattest route. mapmyride.com was not working, but I found http://gb.mapometer.com/en/ which will at least show me an altitude profile of my route:
Depending exactly where I mark the start/finish on the map I get 4.6+ to 4.8 miles, so the distance is up very slightly.
