Scores on the doors.

One year ago today I zeroed my speedo and aimed to crack 5000 miles for the
year. Here is a photo of it this afternoon. Now I'll try and do 5500 or more
this year.

18 miles in 5,018 leaves a margin of error of just 0.36% - or just over 6
yards every mile. Are you sure your speedo is calibrated properly;-)

On a serious note, I really like this idea and am going to do the same -
around 100 miles a week is a very good and realistic goal.

one (and therefore than almost all of the frame) is your speedo's sensor
on the front forks and are you sure that you and the rest of the bike
have done 5k yet?

And if you insist on jumping over potholes and grids like me, have you
allowed for the aerodynamic slowing of the wheel while it is off the
ground? ;-)

I have a back up GPS running in parallel which takes all that into account.

Unfortunately not. GPS works by position change which a) has errors in it
especially at low speeds and b) because of sampling intervals approximates a
curve with a series of straight lines creating an error in the distance
travelled ;-)

Cool - that means he's gone FURTHER than 5,000 miles!

Hi Simon

Nah! It's your clock and it's not operating correctly. What your
computer is telling you is that it's ten to seven in the evening. Or
maybe not.

Congrats, sir.
