He was in Edmonton where they have an indoor 200m flat track (no bank) with about 100m from wall to wall to run 60 to 80m. If they did any running around the oval, it was very easy on the corners with higher speed runs on the straightaways (for Special Endurance work).

When Kevin did coach in Vancouver (not nearly as cold but still rainy and cool in the winter), he was implementing speed work over 30-40m in hallways (much like I have done in the past). The Edmonton circumstances were much better than the Vancouveri situation, but definitely far from idea.
