Bike rides getting shorter?
Hello
Yesterday I went on a 20 mi loop that I ride every so often but this time, my computer said it was a full mile shorter than it normally takes. Usually it wavers from about 20.01 to 20.30 mi but this time it was 18.95.
I only started really training a few months ago, so could I just be riding in a straighter line or should I get my cateye computer checked out?
Did/does this happen to anyone else?
Thanks

Check to see if the magnet or sensor is out of alignment. If it were "missing" sometimes, that would account for the missing mile.

You're so fast you're experiencing Einsteinian time and distance contraction.

Sounds like the wheel size setting is off. Double check the tire rollout and confirm. Do you know how to set the wheel size on your computer?

If you recently changed the battery or somehow managed to reset the wheel circumference setting for your particular wheel size, then your computer will give you inaccurate measures.
Or, what 24tracktape said.
Or, your wiring harness/computer head interface is sketchy. Maybe you could very delicately clean the contacts.
Good luck.

If you were really "squirrely"when you first started logging this ride I can see the distance coming down some (your "normal" waver for instance) but a mile + difference over a 20 mile loop? Unless you used to make some U-turns I think the problem is in your computer.
When the cat-Eye on my wife's bike started acting up after several years (inaccurate speed sensing for the most part) we attributed it to a "natural" death.
