I promoted a Vegas (Jean) to Reno (Topaz) Dual Sport ride years ago. I did it in two days but found it was really a 3-day ride. I avoided the V-R race course as much as possible as it is worse than riding thru hell after the trucks trash the route. Had to use it to get to Mina for gas and riders were pissed. I have the GPS tracks if you are interested. Probably on GPSXchange.com in Nevada Statewide Motorized Trail System.
Actually 2-3 days along Hwy 50 is worlds better riding.
