A good practice hill just off of the BG - immediately after you go through the tunnel (the one about 1/4 mile before the Bothel Landing park - where the chickens are) go straight across the first bridge instead of turning right. Follow the trail until it ends then get onto the road. Go through the intersection with the traffic light. Go just a little further and take a right onto 112th Pl NE, keep climbing by going to the right again onto NE 164th Pl. The street name changes several times, but if you keep on going straight you'll come out to a bigger street which is NE 145th (be careful on the descent, it is fast, winding and you will need to stop quickly at the bottom), take a right to the next street light (you go only about a block on this street) and then take another right onto 100th Ave NE - this is a busier street, but it has a bike lane and will take you back down to the BG trail right at the golf course.

This is a fairly long climb, but it has a little of every thing so its a good one to practice on.
