Into Manitoba but only 45km today. His facebook post seems like his back trouble hasn't gone away and may be with him the rest of the way if he cant get it sorted out:
Hmmm. Road camber might be a reason for the back issues. Running a long distance on a sideways slope is not the best. Taking the TransCan highway I don't see how he can avoid the camber. He could switch sides during the day to get some balance.
