Doing all my updates for 2012 at one time here. I typically don't take the full 31 days, just going from the first Sunday (or last Sunday of the previous month) to the last Saturday of the month so that everythng is in 4- or 5-week blocks. This includes total kilometers from all three bikes I've been riding: the fixed gear (which gets most of the use and is currently at just over 13,000 km), the track bike on the track, and the tandem:
Date: Total: Month:
----- ------- ------
1-28 1,501
2-25 3,064 1,563
3-31 5,123 2,059
4-28 6,962 1,839
5-26 8,770 1,808
6-30 10,884 2,114
7-28 13,006 2,122
8-25 15,044 2,038
Can't quite make the 1,000 miles per month club as I'm a bit short in January & February!
