Catrin,
Just as a frame of reference, we did two very big trail races last year and everybody except the top, top pro-type athletes walked up hills at some point. And I mean everybody. It was hard for me to wrap my brain around at first, but I figured, heck, some of these folks just about do this for a living and they obviously know something that I don't know. When I trained, I tried really, really hard not to walk.

At the North Face Challenge I got on the wheel of this teeny tiny woman that was booking it, and she too walked the hills, HOWEVER, just as she crested, she started to run again. All the other racers would take an extra 30 secs to keep trudging. Just that little tiny difference got her way ahead. So I just stuck with her and it worked. trudge, trudge, trudge and then off you go!

You will do great. If you are running two miles now, you will be fine by race day. Just enjoy your time in the woods before it gets hot. After the winter we have all had, we deserve this time right now. If you have to walk the hills, just embrace it.....trudge, trudge, trudge and off you go!
