OK - this surprises me that these sorts of fixes are available.. so (unscrupulously hijacking the thread), what about a Forerunner 205 that no longer beeps? I read recently that someone else's doesn't beep either... and now I'm wondering if there is a known fix.
Is it a race or a run? Well one question.... do we know if course measurement is taken as seriously as it would be for any other 5K "race"? Undoubtedly the start and finish points sometimes move for practical reasons (boggy ground etc), as they can in any race... but is this done 'professionally' - or do the organisers take the view that it is just a "run" and not so important?
