I too have Blackstar though after downloading GPSlogger I have not use it anymore (tough I like the "export to google maps feature")

In the same spirit of finding a solution I strongly recommend you to try Bones In Motion app. It will track your path and you can set it to "walking" "cycling" etc. You can also see your workout in a chart with pace and elevation, it can also export to map and in theory will tell you burned calories after you input your weight. Its free

Hope this help. Tough I have yet to try it in stand by mode :S
