Bicyling in Reno, NV?

Hi all:

My wife has booked us for two nights in the downtown Reno area. (The
last time we visited she hit some sizable jackpots on the slots right
before we had to leave - the very *best* time to win - so she's
conviced she can do it again.) However, I've just started training
for my first ever century ride and plan to take my bike on the trip.
Can anyone suggest some training routes in and around the Reno area?
The terrain isn't too important, I'd just like to get some miles in
(40 - 50) on some roads where I'm not fighting huge amounts of auto
traffic and where I'm not too likely to get completely lost.

Some general directions in this regard - I can supplement with
MapQuest - would be deeply appreciated.

TIA.
