Not sure if this has been asked already, but a search didn't turn up any answers.
I have a Forerunner 305 that I have had since around Christmas, but this evening was the first time I have really used it for cycling. Due to nagging health problems, this evening was the first time I have done a ride in over six weeks.
I knew I couldn't go far, but I just wanted to get a few miles in before it got dark. Anyway, to make a long story short, my Forerunner 305 says I did 4.23 miles, but my mind says that it wasn't that far. My ride consisted entirely of residential streets with not much tree cover, so I'm sure it was in good connection with the satellites.
I guess my question would be this...when out in the open, so to speak, is the Forerunner 305 pretty accurate? Has anyone had any major distance discrepancies, or does it match up pretty well with a bike based odometer?
Thanks in advance for any info y'all can provide.
