Thursday track session will only happen in the unlikely circumstance that the snow has gone.
The track is presently closed. Forecast are that little will change and the paths in the park are too icy for running.
For a snappy 3km to be run wherever you can find a suitable ice free stretch:
10x200m with 1 minute recoveries at 55 or 40 seconds pace. After 2 minutes recovery 10x100m with 30 seconds recovery (20 seconds pace).
