My cousin just completed a charity ride from Reditch in the Midlands to Valley, Anglesey. 190miles

I'm thinking of sponsoring him per wheel revolution....

I think I've managed to work out that with a 28" wheel/tyre diameter I can pay him 1p per 100 revs to give a total of £14.20p. But my brain was starting to hurt..

Anyone fancy doing some number crunching?

10p a mile or stop being tight and just give him the score note! 😀

Give him the amount of money you want to , explain your rationale, hope he is as bad at maths as you are 😉

190 miles = 305 775.36 metres
700x23c circumference is 2.1 give or take a bit.
305775.36/2.1=145607.314286
1p per hundred turns so 145607.314286/100=1456.07314286
So £14.56 I reckon, could be wrong though.
