Starting on Hobart Issaquah rd at the entry way to Mirrormont housing development (big sign @ Mirrormont entry) take a left. With the first few pedal strokes you'll be on the steepest section of this climb, a measured 21% on the inside of the switchback and the "bump" just a bit higher up on the 1st hill. A decent shoulder and little traffic will take you up the entry way hill. Just stay on the main road and don't bail on the first two right turns where the grade decreases. First one is a dead end the second goes through and can be used as an alternative route. At the first left turn switch back the road turns into 245th Ave and goes uphill sharply (21%). Stay on this road till you crest the hill at 247th. Take 247th to 253 and take a left to join SE Mirrormont Way. Go straight from here up a hill and down and up the final hill to hit Tiger Mtn Rd at the Fire Station. Take a right to get on to 154th for another mile of climbing. Be cautious of the road contions and your brakes if you venture on to 154th. M
