First of all, I foreran that course when I was 6 years old. I was wearing hockey skates, a tutu and a painter's cap. So a 9 year old? Pshhh! Whatevas.
But all kidding aside, other than it being in a National Park, Lake Louise is a very accessible race. In fact most years the general skiing public ignores the race altogether so race fans don't have to worry about finding choice seats. It's a pretty low key affair, especially since it is so early in the year. Most of the course is viewable by skiing beside it.
BUT! It can be BRUTALLY cold here in Alberta at that time of year (or more accurately, at almost ANY time of the year). So come prepared. Bring all your warmest clothes, battery powered boot/mitt warmers, and even face masks if you got 'em. Looks dumb but so does running into the lodge every 10 minutes to thaw your extremities.
That said, apparently few if any World Cup venues rival Lake Louise for beauty, so pray for good weather and have fun!
P.S. I've ran that course many times. While very fast in average speed it is easy as it is relatively flat, and has no radical changes in terrain or steepness. I say it was easy and I pretty much sucked.
