5004 miles (it would have been 5000 but I was 4 miles from home).
My highest ever I think. I work, but don't commute, so I have to 'force' myself out sometimes to keep the miles ticking over, it would be so easy to do a lot less.
Just checked my records and I'm about 3lbs lighter than this time last year but that's still not very good considering 5004 miles cycled.
5004 miles at approx 15mph = 333 hours cycling.
1 hour cycling = approx 400 calories = 133,440 calories
3500 calories = 1lb of fat = 38 pounds.
I guess I must have (over)rewarded myself with 122,000 calories along the way.
