In my experience 4.5 hours isn't unusual for a Garmin.I run a garmin edge touring with radar (older style) and a HRM. Disappointed I only got about 4.5 hours. I hope to follow a route and lead a club run soon - any tips for what settings I can use to improve battery life ?
Turn the radar connection off, and turn the screen off assuming you know where you are going when you lead this ride.
I was wondering is there a mode - where you have the radar only - no light ?
I hadn't thought about the point @Darius_Jedburgh makes above. He's right in my view, relying on a Garmin to lead a club ride is placing a lot of faith in both the Garmin and your own plotting ability.I run a garmin edge explore with radar (older style) and a HRM.
