What specific aspects of urban survival? Long term food production or storage? Water storage, rainwater harvesting and purification? Urban hunting? Space management? Avoiding crime, riots and looting? Home protection? Homeless/transient lifestyle and dumpster diving?
We have threads on most of those items, but if you want specific information on particular strategies, just ask and the members here will give you their best answers. Often that is based on real life not just a book some instructor has read, thus is better than a paid-for class.
Short of putting yourself into the situation and prowling your neighborhood with a tactical shotgun and grey camo BDU's, there is really not a lot you can do to "practice" Urban Survival. Go to the local gun range and practice tight grouping shot placement with various weapons you own, start putting your pantry together for times without power (local emergencies or TSHTF, it doesn't matter as long as you have food and water, right?), getting a warm/cold weather wardrobe together, having an alternate source of fresh water and window-sill gardens/sprouting/hydroponics/etc. for food, learning the escape routes from your building, your neighborhood, and your city and learning the danger zones and bottlenecks that could mean disaster for your evac plans, learning utility shut offs and earthquake/hurricane/tornado procedures in your building, getting smoke and CO detectors and ABC fire extinguishers, getting a stocked first aid kit and learning to do at LEAST basic CPR/mouth-to-mouth/Heimlich manuevers for lifesaving, having a kerosene or propane space heater on hand for electrical outages in winter (well-ventilated spaces only please!), and of course, financial management to have enough money on hand for a couple of months at least if you lose your job, or your workplace is damaged in a disaster rather than your home, etc.
Learning what community programs are in your area are important too. There are Freecycle type barter groups in cities that allow you to get rid of your unwanted items or barter your specific services (work or hobby) for things OTHER members have or can provide. The city is also often home to "block gardens" that are neighborhood volunteer efforts, that can provide food for local residents who help with the chores. Things like neighborhood watch and government CERT programs for Community Emergency Response Teams can prepare you for crisis management in your area and allow you to prepare others in your area for crime and disasters at the same time.
I hope that helps you start out with your plans. There is a book by the same folks who made the SAS Survival Guide, called the SAS URBAN Survival Guide that has a good amount of info for city dwellers.
