my cateye enduro 2 seem to read pretty acurattly to me but recently someone in our club seemed to think the identical ride we had done was quite a bit longer.i spent a lot of time trying to set up mine before use but how can i check its ok? is there a way of checking settings??
Find a local roadie and get him/her to show you one of their time trial routes. That will have been measured to the metre.
Compare it to a GPS. Mine was (By chance) silly accurate last time I did this. Something like 0.1 of a mile over 50+ miles. 🙂
Inflate tyre to usual pressure. Take bike to long straight bit of level tarmac. Rotate wheel until valve at 6 o'clock, mark ground with chalk. Sit on bike and have someone push you forward in a perfectly straight line until the wheel has completed 10 revolutions. Mark ground, measure distance travelled, follow leaflet that came with computer and divide the answer by 10.
Find a measured half mile used by local traffic cops to calibrate their speedos / VASCAR and ride along to check accuracy. Bit tricky on motorways mind.
For long road rides the route plotting feature in Google maps is your friend if you don't have a GPS log.
And I have a standard [url= http://maps.google.co.uk/maps?f=d&source=s_d&saddr=51.248781,-2.646675&daddr=Priddy+Rd&hl=en&geocode=%3BFbDpDQMd1iTY_w&mra=dme&mrcr=0&mrsp=0&sz=15&sll=51.247545,-2.635131&sspn=0.019637,0.048237&ie=UTF8&ll=51.246498,-2.627878&spn=0.039275,0.096474&z=14 ]calibration run[/url] for computers, exactly 2.5km between the junctions.
