I've been doing better than expected this month:

1/2 -- 21.8 miles, 945'
1/3 -- 25.1 miles, 1453'
1/4 -- 46.8 miles, 1654' (should have eaten on this one; last hill before home was tough!)
1/6 -- 21.6 miles, 935' and in the low 30s. Clingfilm wrapping my toes in my shoes!
1/7 -- 21.6 miles, 938', also cold and no I have no cold weather gear.
1/9 -- 21.6 miles, 938'. Weather warmed up and ran it as a tempo ride.

There's a pattern in my riding

158.4 miles
6,887' of climbing.

I'm targeting 600km. Next week is a lot of work travel, so got to stack in the miles early.
