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.

More particularly, since your front wheel travels further than the back 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 ;-)

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.

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

And this is the same Simon Mason who was just going to do get fit enough for one long ride (200miles
wasn't it?), then pack it in and try something else. Golf ISTR.

Seriously, well done, I'll be lucky to get 1800 this year, but its been a [censored] year with some
motivational black holes.
