Tim,
I do a fair amount of XC skiing, but seeing these athletes in action sure gave me a completely new appreciation for the word “determination”.
Part of the competition was biathlon and seeing the perfect shooting results the visually impaired came up with and how they handled the heavy traffic around the entrance/exit section of the penalty loop (for those who missed the target) was just incredible.
BTW the organizers had set up a “have a try” area with one of the laser guns used by the VI competitors. Perhaps I would have had more success shooting prone instead of standing - I hit only 2 of 5 targets. Aiming strictly by the pitch you hear and holding things steady would take some extra practice.
