4000 miles!
 

My computer is now reading 3988.8 miles so I will cross the magic 4000 barrier on the way home.

I got this one in May or June last year and thought that I had used it on our Dutch tour, but my wife reminded me that I used my old computer because I had set it to km.

So 4000 miles commuting = one rear block, new chain, and 3 tyres (2 rear 1 front.)

Wow. 4000 is a lot of commuting miles. Way to go.
