I just upgraded my 310XT to 735XT. I was going to get a FR235, but thought the tri watch would likely be better at cycling activities than the predominately running 235/230. 735 (and 235) have HRM built in, so you can leave your strap at home if you’re wearing on wrist – I still cycle with mine on bars and use HRM strap though. Its good for running.
All the smart features and additional activities/widgets/apps you can add are nice. A bit overwhelming at first, but I have the hang of it. It measures steps and sleep too – the novelty will wear off soon I’m sure, but I’m paying attention to them at the moment. I can also use it for squash and football, so my strava/connect are now getting daily updates 🙂
Only gripe is that it feels a little flimsy. Its so light. Possibly it was made like that for running, but it doesnt feel very substantial.
Oh, another. It doesnt do total altitude gain. Just current. Which on the watch is very off and varied. Once downloaded and on connect/strava it corrects the misreadings.
