I have five Garmins on my bike
One is set to show HR, Avg HR, Max, HR, Min HR, HR of my riding partner
One is set to show Total Elapsed Time, Rolling Time, Rest Time, Clock Time, London Time
One is set to Show Total Dist, Dist for this ride, Dist of last lap, and Dist from previous intersection
One shows Speed in MPH, Speed in KPH, Max speed, Min speed, Avg speed, speed of the car behind me
The last one doesn't work at all but an odd number is more asetically pleasing
Oh yea, I also wear a Timex Ironman Triathalon watch that alarms me every hour.
Once I reset them all and hit the start buttons I don't have any time left to ride.
