A couple of days ago I hurt my left middle finger a little bit and also the right shoulder, but fortunately not serious this time. It happened when I was going at a very moderate speed on a steep, very narrow and icy slope (with only artificial snow) in the wood. My intention was to make a slow heel turn at the very edge of the slope where there still were groomed snow. Instead of turning, the edge catched the snow and I went straight forward and stumbled over big frozen ice lumps at the slope edge and into the wood rolling over my head. Fortunately, I did not hit a tree and only 30 cm from my head it was a big stone. As I wore a helmet and solid wrist protectors nothing serious happened this time but I dare not think what could have been the result without the helmet and wrist protectors.
What do you do to reduce the chance of such injuries?
Since I am not so young anymore (62 years) I need some time to warm up and get used to the snow conditions. So, if possible, I run the first or first two or three runs very calmly, inspecting the snow conditions, testing the grip of the surface, watch out for icy spots, ridges after the pisting machines, holes in the snow, ice lumps or other things that might cause injuries before increasing the pace and going deeper in the turns. And, as I wrote, I wear a ski helmet (started four seasons ago) and wrist protectors outside the gloves (they also are fine for sliding the hands and protecting the gloves as well). In my opinion, injuries can be reduced by warming up before going full speed and taking a rest or cease running when you feel tired.
Luckily, I live only 15 minutes by car from my home to my local ski area, and have a seasonal pass, so it is easy to practice often, relative intense and short sessions before being too tired.
