no access to hills during winter

[ESTI]

@Stikki

Multi level parking garages can sometimes be a good source of hills in winter. Pros: They are dry and often lit at night, and somewhat warm if underground. Cons: Security may kick you out and the surface is concrete.

Henk Kraaijenhof used parking garages for hill substitute. They also did a lot of sprint work inside shopping malls, since there were no indoor tracks at the time. This was done with Nelli Cooman.
