While the Sunrise Trail is described as not "...too burly, but surely burly enough..." I can say that for my December legs it definitely leaned towards the burly! Starting from the Lost Dog Wash trailhead at the end of 124th Street, I knew it would be an out-and-bike ride: Climb up to the top and then rip it back down. What I didn't realize was that the trail, while completely rideable, is extremely rocky and that the final .25 miles to the summit is not intended for bikes. Regardless, the ride was a blast and a good strength workout for my legs. I rode everything on the way up with the exception of a few steep, tight switchbacks and the final .25 miles to the top. I did, however, bring my bike with me so I could get a shot of it at the summit. The handful of hikers I passed at the top were completely amazed to see a rider that high. It was a good, solid ride and as you can see from the pictures (taken on the way down so as not to interrupt my rythm climbing which means that sequentially they are from the top down...) the scenery was fantastic.
