Check in with local cyclists. One of the most popular routes would be the Verdi lap which is a decent training ride but nothing special to look at. Riding south down Lakeside, over Windy Hill, and through the rancho area, and up to Thomas Creek & Mt Rose Hwy is a great ride and maybe you'll even spot the one yak out there. Hooray! Cyclists tend to hangout at Bibo Coffee Company at 680 Mt Rose St or at Walden's Coffeehouse on McCarren and Mayberry. Both of those coffee shops are less than 5 miles tops away from the medical centers around town so you would have no problem just hopping on the bike and going.
