I picked up my afternoon kids yesterday, and Lucy proudly told me that her class had just finished running to Cape Reinga. Which is the northernmost point of NZ. We live in Wellington which I think is about 900km away.
It seems their teacher had them all running around the track each day, and they added up the total mileage of the whole class over a period and found they had run the equivalent of 900k.

I thought if we add up the metres we walk each day, we might be able to walk a long way between us. I suppose the thing to do would be to add your total on to the previous total so we keep it running. Does that make sense? The problem is do we do it in miles or K's if we do it in miles someone will have to tell me how many yds in a mile. I learnt it at school but since we converted to metric I've forgotten
