Garmin - Forerunner 305

Old guy here. I'm tall with thin wrists and even an Apple Watch Ultra looks a little ridiculous on me (to me). Back in the day, our only Garmin GPS option was the 305. It was like wearing a CRT monitor on your arm. *However*, I never really noticed it during training or racing. It was the cost of doing business and my brain just filtered out the proprioceptors like it does with shoes and jackets, etc. Given that almost all the Garmin options are pretty thin, how it looks is likely the only real concern. The diameter shouldn't affect whether it snags on clothing, etc., but you might need a smaller strap. I'd choose the one with the best features for your data-crunching. If you don't need a lot of data, the smaller watches would probably do the job. https://preview.redd.it/8g7pjtsq85sf1.jpeg?width=3024&format=pjpg&auto=webp&s=d11130072d2f69e311abd65ebd09c0478bba4a9c

Garmin faithful (though not fanboy) here… 305>610>935>255s (middle numbers might be wrong and I’m too lazy to doublecheck). Wrist issues are going to happen to a small slice of the population with silicone straps… emphasis on small. As far as training readiness… these are consumer grade devices… squint when the garmin (or coros or suunto or apple or whoever) tells you stuff and you’ll be fine. 

i second that. wrist HR with F8 is also faulty for me like 30% of the times, could be because of a wrist or a strap. But i did not see any with F8 improvement compared to F6 or older forerunners

>Its a Vivoactive by another name. ironically i've been looking at the FR series to upgrade my old vivoactive. lack of altimeter is deal breaker for me.
