I took part in the annual Duo Normand cycle race on 24th September in Marigny, Normandy. Turns out most of the route wasn't on the map.....so I took my GPS with me and it's now added (although still awaiting rendering as I write this). Actually the GPS was my only means of knowing the altitude and hence gauging how far up each of the hills I was, so it was a useful piece of equipment during the race as well. I've also added a route relation to mark the course.

And yes, a finer examination of the GPS trace would reveal that I didn't do it in a particularly fast time!
