Garmin Settings?

Checking out the Garmin while running at IM Louisville.

I had an athlete recently ask what he should have displayed on his Garmin Forerunner 910xt.  Thought it was a good question, so wanted to share the answer here as well.
As a bit of background info I have been using Garmin products since the first Forerunner 101 came out.  Back then it was strapped to one wrist while my old HRM was strapped to the other (I looked like a dork...) I am not as much of an expert as DC Rainmaker (a blog I highly recommend you check out if you are interested in the technology of triathlon training) but I enjoy learning about new technology and how devices can help me and my athletes with our training.
I am currently using the Garmin Edge 500 as my primary computer on the bike and love using the Garmin Forerunner 910xt while swimming and running.  I have the Garmin cadence/speed sensor on my road bike, though on the tri bike cadence comes from my Quarq powermeter.  I've recently added the foot pod sensor for running as well. At races last summer I had the 910xt running in multisport mode for the whole race. I would be totally lost without my Garmin devices, don't know how anyone could make good decisions to race effectively without them.

As for what to "watch on the watch", it is all personal preference and some are a bit obvious but the ones I strongly recommend are in bold -


Bike 
Screen 1 - 3” Avg Watts, HR Zn, Cadence, Speed; 
Screen 2 - Total Distance, Lap Avg Speed (I auto-lap every 10-15 miles), Total avg speed, Total Time, Normalize Power Lap
Screen 3 - Time of Day, Calories burned, Temperature


Run
Screen 1 - Lap Distance (I auto-lap every mile), HR Zn, Lap Pace, Lap Cadence
Screen 2 - Total Time, Total Distance, Total Avg Pace, Total Average Cadence
Screen 3 - time of day, Training Effect, Calories burned.

When I go to a hilly place like Colorado I will add elevation to the bike settings.  When I was riding last summer in KY and in Maryland I added elevation gained to my third bike screen just for curiosity, but around Kansas City I find its sort of mute, at least until I get home and upload the file.
I have my devices set to Auto-pause while I'm training but on race day I obviously turn that feature off.
Please feel free to add a comment below if you have other suggestions regarding setup, always open to ideas.
