I commute by bicycle about 42 kilometres (26 miles) round trip, 5 days per week. The roads are well paved, with some rolling hills.
Kate I battle with this problem too. I have found the Iron issue to be extremely important. I actually notice more of a drop in energy a few days before menses than after. I can only guess that it is my body stealing all my iron away from me and along with it my desire to move. I commute 4 - 5 days a week too I understand how the energy thing can be a real pain. When it is getting near that time I try to drink extra water, I'm not sure how much water we really lose but I can tell the way my muscles feel I'm dehydrated sometimes. I make a point to drink an extra glass or two (water bottle or two) per day. Don't beat yourself up too much though, during that time is prime time to pick up bugs if your immune system gets low. Take care I hope that helps some.
