Yes, I have received the Xmas present, a ticket to Antarctic Marathon. And I am going to do it. More running than biking lately and totalled 180Km this month already on my feet. Feeling great as agreed with my new running coach on the plan. Latest 6 hour biking marathon was last November, and i felt tired but great. Hope i can do Antarctic in less than 6 hours:) Woohoo, hope i will not only do it, but come back with a positive story to share with MS community:).
