##$&^#&*^$*@&#$ it's hard!!!! but it opened up the possibilities of what I'm capable of, and I certainly surprised myself.
I finished, but I found the cut-offs quite harsh and put alot of pressure on me, which I didn't find very enjoyable. And you might wonder if that distance it is ever enjoyable, but yes, I do find it fun when I can take my time, enjoy the views, take pictures, eat properly, not feel sick for hours on end, etc etc :)
