Bike shot.

Lacrosse is about the same in Edmonton. I can get shutter speeds slightly faster than the TO arena though with a 70-200 F2.8.

Those images were shot with a 200 1.8. 1/500 sec. @ F2.2 @ 800 ISO

The 70-200 is almost useless in that light, especially because you get no reflection of light from ice.

Here is a recent portrait I did of my cousin on the bike he built. Portraits are not my strong suit, but I think this one isn't half bad.
