What I do (as I generally race with a separate Edge on my bike as well) is get everything all turned on beforehand. Ensure that it has satellite lock in the location and validate that all the sensors are working (quick and easy).

That way, if it turns off due to power save, I simply turn it on as the very first task when I arrive in transition. That takes perhaps 2 seconds to press/hold the button on. Then I go back to getting my wetsuit off/helmet on/etc…

Now, I hadn’t thought through taking it on the run to be honest. It depends a bit on how you want to ‘save’ the data. Personally, i’d reset the activity and start a new one. The reason being that it’s a bit of a pain to splice the data up (not impossible, tools like Golden Cheetah and Sport Tracks can do it just fine), but in general it’s a pain.

But what you could do is go ahead and stop it when you hit transition, then reset it. After racking your bike and just before you leave (or as you’re running out), go ahead and start a new activity. She’ll get notifed then and can follow that for the run. Obviously, with a little practice you shouldn’t lose any time. For me at least, once I’ve started the run, I can do whatever I’d like with my hands – so you can sort that all out as you’re running that first few hundred meters.

Hope this helps!

With the 910XT and the quick release kit, you’ll get a nice compact unit on your stem/handlebars that looks almost like the Edge 500. Now the Edge series allow 8 data fields per page at once, versus 4 for the FR910XT (though both allow multiple data pages).

Given you’re a triathlete, I’d upgrade from the FR305 to the FR910XT. For two reasons, one because you’ll benefit from the additional functions in the pool with the 910XT (you wouldn’t with an Edge), and two because if you’re willing to part ways with little-red (the FR305), you can get another $50 back – bringing it down to $250 all in.

Hope this helps!

The only scenario I could think of on the Edge 800 side would be if you like topo maps while mountain biking. This tends to be focused on folks doing longer trips though in unknown areas, rather than just loops in a local park. Make sense?

Since you already have the 310XT, the 910XT would primarily give you the additional indoor swimming functions (since you don’t have a power meter).

Whereas the Edge 800 would giving you mapping and navigational/routing capabilities while on the bike. So it comes down to whether you want indoor swimming, or mapping on the bike.

Hope this helps!
