I think the watches (we both have Apple watches) will be fine for most of our cycle training (which I'm assuming will be mostly 1-2 hours), but I'm not sure how they'll do battery-wise for 75-100 mile ride at what I'm assuming will be 14-16mph. I assume the GPS will run the batteries down pretty quickly. If we could get a full days ride out of them, then we could probably carry a spare battery to recharge them that night. I could disable things like wifi and bluetooth to extend the battery life, but I'm not sure if it would be enough.

My watch is a Garmin Forerunner 35, a few years old now, cheapest GPS watch at the time, Bluetooth synch to my bike computer a Garmin Edge 520, smallest and cheapest at the time that has mapping available. I like the watch because though it has GPS it also learns your stride and can work indoors w/o the GPS.
I do a 3 to 4 hr ride almost daily in nicer weather, the 520 isn't even close to out of juice, it gets charges when I connect to the home computer to upload data after a ride. The 35 goes days w/o a recharge though I usually take it off and charge over night. It's interesting to see the watch data after track days and ski trips.
Here's a typical ride, HR wasn't being monitored that day because it was just a relaxing fun ride w/ a few friends
