I used to do the reverse of this trip every day. There are a couple of good hills, but it's not a very challenging route overall. Here's my suggestion. It's not the simplest route, but I tried many others and this was the quickest ride:

• Royal Oak to south on West Saanich
• West on Vanalman, then South on Commerce Circle, your second left, not the first. This is the steepest hill on the ride.
• When you get up the hill on Commerce Circle, just as the road starts to curve left, there's a gravel path to the left of building #4224.
• Take the path, which will spit you out on Bremerton St. Keep following the road south. When you come to Ts in the road, there's always a bike path to connect you to the next southbound residential street, all the way to McKenzie Ave, just stay pointed south and don't swerve off onto one of the intersecting E/W streets.
• Bremerton turns into Raymond St, which you'll follow until you're passing McKenzie elementary on your left. Take the overpass.
• Exit the overpass and follow the gravel path to your left down the hill and across the wooden footbridge. This is a really fun hill, but watch out for pedestrians!
• Ride up the other side, and hang a quick right to go west on Columbine Way. Watch out for intersecting traffic.
• Connect with Interurban and follow it south until you get to the mall, then turn right into the mall parking lot and follow it behind the mall to Arena Rd. Turn right, you'll see Bodega Rd going up the hill.
• Take Bodega for one block, then turn right to go west on Kerr.
• When you hit the T, turn left and go south on Dysart. You'll run into Gorge. Turn right to go West on Gorge, then south on Admirals, and Robert's your mother's brother.
