I'm setup for a third attempt at getting eBrevet to work. The past 2 times I have used it the start validates fine, but the distance is way off when I get to the second and subsequent controls, even after checking that the phone knows my location, and giving the eBrevet app a few minutes. I have now changed the security setting to give eBrevet 'Always' access to location services, and not just whilst using the app. Maybe that will help.
Ignoring the wind, dampness and chill, it should be a good day out on the first of this year's winter series.
