The first couple of runs were good, then as the visíbility on the top of the hill (I refuse to call 500m a mountain) dropped so you could read the run a good 3m ahead of you I set off...
Now, doing this particular run (7,3 to its friends) earlier in the week was pretty straightforward, but I'd seen a poor chap ski too far left and end up in a snowdrift, so with visibility low I aimed right. Just, erm, too far, and ran up a hill, then fell down, on my right knee. Then I sat down for a bit and cursed for a minute or two.
It really quite hurt. And now I have "dimple" on my knee rougly the size of half an apple. Actually, that probably overstates the damage but I'll get sympathy where I can.
Anyway, I did the run later again with no problems (I had to stop myself being scared of it) and tomorrow is high speed snowmobiling. If I run one of those up a hill I expect more than a bruised knee...
