Well that is a pity, yesterday I mucked about with the Garmin was trying to figure out Virtual Partner (I Know RTFM) well I loaded my fastest ride in as a course and couldn't get VP working got distracted and just turned off the Garmin. Started riding this morning and I was getting turn by turn all the way to work.
1. It was very annoying turn by bloody turn beeping like mad
2. It seems to have missed loads of Segements
3. It was a record run so should have had a few PR*
*I would like an opinion please I increased my Wheel size to 2110 on the Garmin (Conti GP 4000 700c x 23c 120 PSI) The Side of the box the Conti came in gave the rolling MM as 2133 I assume with weight that decreases.
I reset my trip on the Car yesterday and drove my exact route home, the car recorded 16.8 miles, my Garmin has been recording 16.4 to 16.45, This morning having changed the wheel size 16.53.
Am I kidding myself? Would the Car be .20 over or more than that? I assume the miles would not be spot on in a car as the Speedo on cars as always a bit OTT?
