I have an Edge 705 which has a Laps button and facility.
I'd originally thought this ewas for doing the same route over and over again on a ride, however I wondered if it might be used in hte following way:
Lap 1 - Ride to start of Audax
Press Lap Button
Lap 2 - Ride Audax
Press button
Lap 3 - Ride Home.
Would this give me three separate ride logs, with an overall summary for the day?
