How many miles have you travelled till now?

I think that as I have traveled to many places in the world in my life this would be very challenging to work out. The only time I worked out the number of miles I traveled was when I flew around the world. I think in hours when I fly. I know how many hours I will be in the air for. I do not usually look at how many miles I travel. When I was in Belize I saw a fun sign showing the direction and distance to places like London, Paris, Rome, New York, Sydney, Auckland and so on.

I have no idea but just cycling to work I've covered more than 30,000 miles in the last 11 or 12 years (3000 miles a year) I also fly to America twice a year and so far I've made 12 or 13 trips at 8000 miles for the round trip so that's probably getting on for 100,000 miles...
