Route summary predicted times

When a route is created there is a summary giving distance and then in brackets a time. The time appears to be based on an average speed which is entered in the user profile. In most cases this is reasonably accurate and, for me, in hilly Devon and 65 years old, 12 mph is usually fairly accurate. But if I have a route climbing Alpe d'Huez then 40 minutes is not an accurate prediction and even in Devon rides can feature more or less elevation. I realise that there are other factors involved, road surface for example, but would it be possible to get the predicted times to consider elevation? I'm wondering if in the profile a user could enter data from a couple of rides giving distance, elevation and time taken. This could then be used to make predicted times more accurate?

Thank you for all the work you do which I believe has made  cycle.travel the best tool for planning a ride.

Maps for Garmin edge

I hope nobody minds me asking a Garmin question rather than a cycle travel one, but this forum seems to provide helpful answers and I am not sure where else to turn.

I have always downloaded maps for my edge 530 from http://garmin.openstreetmap.nl/ as it's easy, up to date and I can get a map of the area I want rather than the whole of Europe which Garmin provide through the annual updates. However, when I tried to do this a couple of weeks ago, I got put in a queue of over 600 days. Thinking this was a mistake I waited, but it appears that something is wrong as no email has arrived telling me it is ready to download. It also appears that downloads now have to be of entire countries rather than smaller user generated areas.

I would be most grateful if someone could tell me if there is a way to make this site work or let me know of other sites with free routable maps, preferably with a cycling layer. My main concern is file formats. I worry about putting something inappropriate in my edge and finding I no longer have a map.

And, while I am here, I would like to take the opportunity to thank Richard for cycle travel and the continual improvements he is making to it. I particularly like having elevation in feet as I am somewhat old fashioned.

CT files and Edge 530

Apologies if this has already been answered somewhere. After creating a route on Cycle Travel I download the tcx course file to a Windows computer, then copy it into the New folder on the Edge. Looking at the route on the Edge, in the summary section it gives distance correctly but gives ascent and descent as 0 feet. This is Devon so that is not right. The elevation section shows a horizontal line. However, the climbs are shown correctly. Now I can get round this by copying the files into Garmin Connect and putting them on the Edge from there. All the data now appears correctly. But, if I want to make minor changes to the route I cannot makes them on the Garmin as a small change can have major consequences elsewhere in the route. I assume that is because although the route is copied to Garmin Connect the points are not. So to make a change it is back to CT and then all the transfer and copying of files. Has anyone else had this problem or, even better, found a solution?
