Bike computer is dead. Will my Garmin Forerunner 230 work well on the bike and run combo?

I've never used it in bike mode as I had a 510. I assume any aero issue from wearing a watch is negligible for a 5+ hour bike leg guy. Specs say the battery will last but looks like I'll just have to remember to change the settings between bike and run. Also will be a minor difference turning the wrist to see speed. FYI - no power for races, I like to go by feel.

Thanks for any input.
