I talked about this a bit in the get healthy post

Jogging on a bright November morning

My biggest challenge right now is preparing my body for the Half Marathon (21.3 km) I will be walking in on May 1st. Yesterday I did a training walk and managed 17km. I know I can do it. This marks the end of "the Biggest loser" competition at the Gym where I belong. The contest has been running since January, I have done pretty well, I know I am a lot fitter and have tons more energy. The reason I took the challenge is because my husband and I are taking a four month trip across Canada and into the Arctic. We will be doing a lot of hiking and I wanted to have enough endurance to make it up a mountain or two.
