Hmm, that's what I feared. I'm trying to justify a 735 over a 235, but geeking over numbers doesn't really cut it. But the 735 supposedly has better navigation and no longer missing turns is a better justification for the €100 premium. So I think I'll go for it.
Anyone using a watch that features Garmin's Running Dynamics? Have you been able to use the data to significantly improve your form?
