The girls aren't working particularly hard, but they are being very careful to make sure they get enough sleep. The first two pictures show them having a post breakfast snooze - note how Madam is posing for the camera as usual. The last picture shows them just after an exercise session. Madam appears to be asleep on her feet!
They are currently working 5 days a week and are racking up about 25 miles a week, our target is to average 50-70 miles a week, so we have a way to go yet.
